Did you try building without using the --with-framework-name option?
That's not an option that gets tested much.  There should not be a need
to use it since different versions of python (2.6, 2.7, 3.1, etc) can
co-exist without problem in the same framework.  The only potential
issue are the unversioned symlinks in /usr/local/bin/, i.e.
/usr/local/bin/python will likely get overridden by the most recently
installed python 2.x.  Either adjust manually or stick to using the
versioned symlinks, /usr/local/bin/python2.7 etc. or set your PATH to
put the appropriate framework bin directory prior to /usr/local/bin.  If
it appears that the --with-framework-name option is the problem, please
open an issue on the python.org bug tracker.
