[gentoo-user] problem compiling Avahi

Hi,

I have problem to compile Avahi. As far as I see there was several bugs
related to this package in the past, so I've tried to perform the steps in
those bug reports to fix this issue (recompile python, python packages,
playing with useflags etc). Unfortunately I can't make it work, so I removed
avahi from useflags, so my world compile is ok. However I would like to use
it, so if anyone has any idea how can I fix it, it could be great

I think the most important part is

configure: error: Could not find Python module dbus

however dbus python is emerged and exists

however when I import module I've got this


>>> import dbus
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.6/site-packages/dbus/__init__.py", line 100, in

    from pyexpat import *

Here is my output of emerge of avahi

An undefined symbol error means that something has changed since that library
was installed.  The solution is to re-install that library, which means re-install
the pyexpat package.  I'm guessing that revdep-rebuild would do that for you
automatically.  You might want to run redep-rebuild anyway because you may have
other broken libraries on your machine as well.

I think the package is called pyxml? emerge -1 pyxml, then revdep-rebuild.

Also, OP should be aware of the USE flag changes for
ucs2/wide-unicode. A snippet from dev-lang/python's ChangeLog (also
see referred bug report):

  06 Dec 2009; Arfrever Frehtes Taifersar Arahesis <arfrever@gentoo.org>
  python-2.4.6.ebuild, python-2.5.4-r3.ebuild, python-2.6.2-r1.ebuild,
  python-2.6.2-r2.ebuild, python-2.6.3.ebuild, python-2.6.4.ebuild,
  python-3.1.1-r1.ebuild, metadata.xml:
  Remove "ucs2" USE flag and add "wide-unicode" USE flag (bug #293135).
