Looking more closely, there is an even simpler way than that of
pychecker. Something like this should directly work:
        python -m Gnumed.wxpython.gnumed

I don’t have one handy, but the idea is to consider it a regular script.

Looking more closely at gnumed.py, it occurs to me that it is not even
meant to be in a modules directory:
        if __name__ != "__main__":
                print "GNUmed startup: This is not intended to be imported as a module 
        
This way, instead of a wrapper script, you could directly put this
script in /usr/bin, adding to it the necessary logic to read the
configuration.

This is very simple, just ship the modules to /usr/share/gnumed-client,
and modify your script to do something like:
        import sys
        sys.path.append("/usr/share/gnumed-client")
        import Gnumed.whatyouwant
        …

Python-support will handle this automatically; you just have to pass the
installation directory to the dh_pysupport call if it is non-standard.

Thanks for your quick answer,
