Just went through this myself.

distutils isn't doing it.  PyOpenGL is (and shouldn't be).  Putting
explicit link refs to /usr/lib is bad on IRIX.  The linker adds the correct
path based on the active ABI setting (-32,-n32,-64,$SGI_ABI,etc.).
distutils uses the compile/link flags that Python used for it's build, and
that is sufficient for compiling/linking a compatible module. 

For now, apply the attached patch (a hack) if your Python was built with
the n32 ABI.  You may be able to null out library_dirs completely, but I
didn't try it.

You may run into other problems later when you try to run the demos though
(I did).  Here, PyOpenGL 2.0.0.44 is building a
site-packages/OpenGL/GL/__init__.so shared object file, which Python 2.1
ignores (reporting that there is no GL module).  Never heard of
__init__.so, but maybe it's something new (?)  I haven't looked into the
fix for this one yet.
