Dunno.  You could file an issue with the MacPorts project.  It seems 
like they've added explicit links to /opt/local/bin for most of the 
ports that include Python scripts.  But that doesn't help if you are 
using easy_install or pip to install other Python packages.  For 
supporting switching between MacPorts Python versions, you can 
substitute "Current" for "2.6" in the above path; I believe "port select 
python" updates the "Current" link to point to the selected version.
