That's a python from python.org, not from MacPorts.

You have (at least) three pythons on your Mac: one from Apple
in /usr/bin, one from python.org (the one you found) and one
from MacPorts in /opt/local/bin/python

You may want to add /opt/local/bin to the front of your PATH;
that will also pick up the MacPorts version of other software
you've installed from MacPorts.

Or you can explicitly type the full path of the python you want.

Or you can define aliases, for example:

alias apple_python=/usr/bin/python
alias macport_python=/opt/local/bin/python

lfpv=/Library/Frameworks/Python.framework/Versions
alias python_org_python=$lfpv/2.7/bin/python


Hope this helps,
