Mac server - Module ir not found

[mguthart]

I seem to recall there being an answer for this, but I can't seem to
find it so I'll ask...

Did a new installation of trytond on a Mac Lion (10.7.2) machine using
MacPorts python 2.7. Everything appeared to install fine, and
installed some various modules. Tried to start trytond and found I had
to install py27-psycopg2 - okay, no problem...installed that. Went to
try and start trytond again and I get the following:

sudo /opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/
trytond

I'm sure it's something fairly straight-forward, but I can't seem to
identify what to try. Thoughts?
