Not knowing Python--and more specifically Python on OS X and even more specifically, Python on OS X via MacPorts--I am at a loss as to the proper method to install Myth's Python bindings.

The python portgroups might help you:
_resources/port1.0/group/python*
For python > 2.5:
default destroot.destdir {"--prefix=${frameworks_dir}/Python.framework/Versions/${python.branch} --root=${destroot}"}
