build python source

[Mark Brethen]

I’ll try to be more specific. This python source does not seem to set the build env. and I don’t see how the python port group will do that. I think the build command needs to set be to "./qreduce.py” and the library path set in “qrmodel.py”. Do I understand this correctly?
