Try setting PYTHONPATH to python.prefix (which is defined in the python
groups), ${frameworks_dir}/Python.framework/Versions/${python.branch} (where
python.branch would be 2.6 in this case).  So something like

configure.env PYTHONPATH="${frameworks_dir}/Python.framework/Versions/2.6"

Since there is no ${prefix}/lib/python2.6 and hence no site-packages under
that, if you can't specify the python prefix separately, using PYTHONPATH
seems like it may work.  And in case anyone asks, using a symlink in
${prefix}/lib for python2.6 won't work or we'll run into the python25 issue
of 'not a directory'.
