[PyQt] sip module shared between multiple python installs

[Hans Jørgen Kjærnet]

Hi,

As we are using different versions of python in our Studio, we would
like sip to be installed into ONE common location.

Here's a list of our pythons:
python2.5.1 - compiled from repository and installed into a shared
network location
maya2009-python2.5.1 - The program we use for 3D (Autodesk Maya
2009)This is the python2.5.1 that comes with maya and resides under
the maya location. It's a built in interpreter.
nuke5.2-python2.5.1 - This is the python2.5.1 for nuke (The Foundry,
Nuke). Also a built in interpreter.

So, my initial thought was to compile and install sip (4.10.1) into
one common site wide location (so there will be less maintenance),
say: /net/share/python/site-packages, and have
PYTHONPATH=/net/share/python/site-packages.

However, sip will only work for the python interpreter that was used
to compile sip. In this case, let's assume I'm using the self compiled
python2.5.1 from the repository. When I try to import sip from inside
maya or nuke, I get a "Undefined symbol: PyUnicodeUCS2_DecodeLatin1. I
figure this is becasue it can't locate the libpython.so in the
self-compiled python2.5.1. Setting LD_LIBRARY_PATH doesn't do the
trick either - besides, I really don`t want to have LD_LIBRARY_PATH
configured.

I did install sip for each of the pythons, and it worked. This is what
I would like to avoid as it presents an extra step of maintenance when
dealing with upgrades.

So, question:
Is there a way to have the sip module shared between multiple
instances of python interpreters - and if so - what's the best way to
do this? FYI, PyQt works fine from a single site wide location.

Takker og bukker,
