[gentoo-user] python 2.6 and python-updater

I've just updated from python-2.5 to 2.6.  Since emerge ran fine, I
ran python-updater.  It's encountering problems with lots of
packages.  For example, "emerge -1 setuptools" ends with:

########## begin emerge output ##########

This looks like a permissions problem
in /usr/lib64/python2.6/site-packages/.  I normally run emerge as
'relson', but this time I ran emerge as 'root' -- so I don't think
it's a simple permissions problem.

Has anybody else emerge python-2.6 and run python-updater?  Any idea
of what I may be doing wrong?  Is it time to head for bgo?

David

http://bugs.gentoo.org/show_bug.cgi?id=240149 identified the fix!

When python2.6 was installed, the entry in /usr/bin was created:

$$$ ls -l /usr/bin/python*

  lrwxrwxrwx  1 root root ... python -> //usr/bin/python2.6
  lrwxrwxrwx  1 root root ... python2 -> python2.5
  -rwxr-xr-x  1 root root ... python2.5
  -rwxr-xr-x  1 root root ... python2.6

The "//" in the symlink causes the problem.  The problem was fixed
with the following commands:

   root@osage portage # eselect python list
   Available python interpreters:
     [1]   python2.5
     [2]   python2.6 *
   root@osage portage # eselect python set 2

so /usr/bin now has 

  lrwxrwxrwx  1 root root ... python  -> /usr/bin/python2.6

(with a single slash) and all is good!
