My guess is MACOSX_DEPLOYMENT_TARGET: this is set in the environment by distutils.

Is that the system supplied version of Python?  Distutils sets MACOSX_DEPLOYMENT_TARGET to 10.4 in that case, for home-build binaries the variable is set to whatever the value was at configure time, defaulting to 10.3.
