py-psycopg2 for Python2.5

Hi, I need py-psycopg2 for Python2.5 but the one in the repository depends on python24. I edited the Portfile and changed this to python25 and did a port install. Python2.5 was correctly downloaded and installed but psycopg2 build failed as it was looking for /opt/local/bin/python2.4 instead of python2.5. I was able to build psycopg2 directly in the work folder, I'm just wondering how do I configure it so port will install it too. Thanks, -John K
