 > I knew there could arise issues from installing libs in System paths
 like /usr/local. But honestly I did not think this applies to Python as
 well. I assumed the correct "site-packages" to use is determined by the
 interpreter you are actually calling, and for a `py27` subport I would
 have expected it to be python2.7 from Macports. And I you would like to
 use packages at other locations, these would need to be tight in
 explicitly.

 of this stuff, but for sure not all.

 Unfortunately, that assumption is wrong. As cal mentioned above, you can
 try `port -t` when MacPorts 2.3 comes out (or install from a trunk
 checkout). The safer (though, more tedious) approach would be to clean
 this system thoroughly. The usual suspects are:

 * `/usr/local`
 * Ruby packages
 * Python packages
 * Haskell packages

 Sometimes, you can use the `pkg` command to determine what packages were
 installed previously. Good luck.
