Unfortunately for your case, Python needs to be built early in the process or dependencies get screwed up, so you should wipe out your source and installation (prefix) trees and start over, with python in the list of modules to build this time. The list I just used is:
>> meta-gtk-osx-bootstrap, python, meta-gtk-osx-core, meta-gtk-osx-python.

When that happens (and it doesn't every time) I clean and rebuild python from the shell:
  [1] Rerun phase build
  [2] Ignore error and continue to install
  [3] Give up on module
  [4] Start shell
  [5] Reload configuration
  [6] Go to phase "wipe directory and start over"
  [7] Go to phase "clean"
  [8] Go to phase "distclean"
choice: 4
cd ../Python-2.7.3
make distclean && ./configure --prefix=$PREFIX --with-system-expat --enable-shared && make && make install
exit

The prompt above will get repeated; pick 7 and it should be happy.

Hmm. That's gotten pretty stale: I think I need to redo the whole lot of it from a Lion-and-later perspective with additional information for Tiger and the Leopards.
