I created mine as an egg, 'getpaid.gst' which is probably what you also want to do. If I recall correctly, I made the basic structure with Paster's 'basic namespace package' or similar (eg: python-2.4.5/bin/paster create basic_namespace). Then add it to your buildout as a development egg. Erm, if you aren't too familiar with buildout then you may be in for a little bit of a learning curve... :-/
