Comment(by deric@…):

 The `python_select` port in macports will allow you to easily switch
 between different versions of python installed by macports and the apple
 supplied one. This checking of MACOSX_DEPLOYMENT_TARGET is a bit dubious
 imo. since the site module always is imported automatically during
 initializtion and the getuserbase call then will import the build
 configuration and bail.

 Basically any environment with MACOSX_DEPLOYMENT_TARGET set to something
 below what python2.7 was built with will not run. Another quick workaround
 is setting MACOSX_DEPLOYMENT_TARGET in
 /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/config/Makefile
 since that's where sysconfig is getting the value from.
