No.  Python doesn't import .so files in a zipfile (such as a .egg file), 
and when the file is extracted, .so files take precedence over .py files, 
so the .py is ignored in that case.

The problem here is that Python's import machinery ignores the word 
'module' in the .so file name, but not in the .py file name.  It looks like 
I need to change bdist_egg to handle this, and possibly some other code in 
setuptools as well.

In the meantime, you should be able to 'import pylircmodule' and have it 
work, or re-install it using -Z (--always-unzip) so that it is installed as 
a directory instead of a zipfile.
