The mention of "/Library/Python" in your output above makes me think you aren't using MacPorts' version of python27. Either run /opt/local/bin/python2.7 directly or use "port select python python27" to make /opt/local/bin/python a symlink to it.

I'm not familiar with j2py, but if it's this:

https://code.google.com/p/java2python/source/browse/trunk/bin/j2py

then its first line of "#!/usr/bin/env python" means it is running "python", wherever that is in your PATH, so using "port select" as above should help it to run MacPorts' python instead of OS X's python.
