It should. There is a demo on how to bundle, using "pygtk-demo" app ?
It includes a new Python installation, rather than using system Python.

If there's something wrong with it (gtk-mac-bundler, nee ige-mac-bundler),
you should report those bugs to the gtk-osx tracker and mailing list...

There is nothing wrong, just that the package I did does NOT support
relocation but has /opt/gtk hardcoded in the code and in the linkage.

And on second thought, I don't think it's all that useful to add it...
If you want to bundle Python/PyGTK, you can use the gtk-mac-bundler ?

But I've added the extra flag (-headerpad_max_install_names) to LDFLAGS,
so if I do rebuild it (for whatever reason) it will be relocatable then.

And added the "binary relocation" support to pkg-config and to gtk+,
so that it will allow relocation - just like it did on Win32* already...

The main problem is that it uses the executable, not the gtk library!
So it still fails for an uninstalled app using a system installation.

The installation is contained within /opt/gtk, so deleting that is
enough to "uninstall" even if Installer.app doesn't allow uninstall.

If you really want to clean up the (harmless) redirection links too,
you also need to remove any / all of the following six .pth files:

/Library/Python/2.5/site-packages/gtkredirect.pth
/Library/Python/2.6/site-packages/gtkredirect.pth
/Library/Python/2.7/site-packages/gtkredirect.pth
/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/gtkredirect.pth
/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/gtkredirect.pth
/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/gtkredirect.pth

Those are just one-liners, so deleting them is more for removing
that extra /opt/gtk/lib/python2.?/site-packages from PYTHONPATH...

There are two locations, one for /usr/bin/python2.? and one for
/usr/local/bin/python2.? (from http://python.org) if using that.
