[gentoo-user] broken python howto

[Daniel Iliev]

Hi, everyone

I'm facing the following problem:

emerge "<whatever>"


!!! Failed to complete python imports. These are internal modules for
!!! python and failure here indicates that you have a problem with python
!!! itself and thus portage is not able to continue processing.

!!! You might consider starting python with verbose flags to see what has
!!! gone wrong. Here is the information we got for this exception:
    No module named time

Traceback (most recent call last):
  File "/usr/bin/emerge", line 28, in ?
    import portage
  File "/usr/lib/portage/pym/portage.py", line 20, in ?
    import copy, errno, os, re, shutil, string, time, types
ImportError: No module named time


How could I fix this? I found an official "howto" on recovering broken
portage but the problem here is with python, isn't it? I have no
experience with python other than using the python based tools of Gentoo
(such as portage itself) therefore I'm helpless.

Any ideas and/or suggestions will be much appreciated.

The Last time i had one of those problems I cracked out an old binpkg
I had lying around ( a lesson I learned a while back on freebsd when i
had make,gcc and tar ALL break due to a common lib dying : moral of
the story: always have static copies of tar/make/bz2 in binpkgs :| )

I know its a nasty solution, but in times of desperation, a manual
untarring of a binpkg into the right place will save you much anguish.

I've not read of any other way to save that problem, other than
hacking up a recent "snapshot" and copying the files into place.

I'm sure theres a better answer than this, but I've yet to see it.

First question: what did you do?

        # python
        Python 2.4.4 (#1, Jan  2 2007, 19:55:21) 
        [GCC 4.1.1 (Gentoo 4.1.1-r3)] on linux2
        Type "help", "copyright", "credits" or "license" for more
        information.
        >>> import time
        >>> time.__file__
        '/usr/lib/python2.4/lib-dynload/time.so'

Make sure that file exists and that the files that it links to exist.

Thanks for the reply.

Yes, I keep this solutions as my last resort before full reinstall. I
just didn't want to take rash course of action before asking for advice
here.

First of all thank you very much! :))

Actually I don't know what happened yet. I have another system with the
same hardware, the same software configuration and almost the same world
file. The first thing I checked after your message was:

 "ls -la /usr/lib/python2.4/lib-dynload/"

on the broken system and it showed an empty dir. Next I made the same
check on the healthy system and it was full of files including
"time.so". So, I transfered the whole directory to the broken system and
now "emerge" works fine (at least at first glance).

Thanks again!

Strange.
I did

 "qfile time.so"

on the healthy system and it gave no results. Also I did

 "qlist python | grep time.so"

and it gave no results either. I suspect something went wrong on both
systems but I'm not sure what and how to fix it.

Even more strange.
Before sending my question here I tried

 "quickpkg python portage"

and extracted the contents of the archives in the root ("/") dir of the
broken system. This action didn't help. After your answer I checked the
contents of the packages made by "quickpkg":

localhost / # tar jtf python-2.4.3-r4.tbz2  | grep lib-dyn
./usr/lib/python2.4/lib-dynload/

bzip2: (stdin): trailing garbage after EOF ignored

localhost / # tar jtf portage-2.1.1-r2.tbz2  | grep lib-dyn

bzip2: (stdin): trailing garbage after EOF ignored


It appears that python only creates this directory, but I can't figure
out which packages put files in it.

Is it normal?

You didn't do something crazy like put "-static" in your CFLAGS did you?

No, I don't have it in my CFLAGS:
grep CFLA /etc/make.conf
CFLAGS="-march=pentium2 -mmmx -pipe -O3 -fomit-frame-pointer"
CXXFLAGS="${CFLAGS}"

(yes it's an old Compaq Pentium II @400MHz with 128MB RAM serving it's
last days as a gateway)

...but I do have "static" in mu USE flags. Forgotten there for may be a
year or so when I wanted a static busybox for init-fs. Until now I never
had problems with that system - every day it gets synced and almost
everyday I do "emerge -DuN world". I don't see "static" USE flag showing
up in python and I guess its disabled by the ebuild:

emerge -pv python
Calculating dependencies ... done!
[ebuild   R   ] dev-lang/python-2.4.3-r4  USE="gdbm ncurses readline ssl
-berkdb -bootstrap -build -doc -ipv6 -nocxx -tk -ucs2" 0 kB

Is this USE flag a problem?

shouldn't -mmmx be -mmx or have I been looking at too many switches and
use flags and going cross-eyed?

When used as a CFLAG it should be "-mmmx" (according to "man gcc").
When used as an USE flag it should be "mmx" (according to "euse -i mmx").
