Ok so I have succesfully bundled my application on 10.5.8 but now we need a 64-bit distribution too so we are trying to build it on 10.7.2 . This comes from what I see with a default 64-bit python 2.7.1 and a py2app 0.5.3 as default.

Now the problem is we need to use the 'python' generated in /Contents/MacOS/python to spawn additional processes(again this seems to work in 10.5.8 generated packages), but now I get:

Could you create a small example project that demonstrates the problem and either mail it to me or file a bug at <https://bitbucket.org/ronaldoussoren/py2app>?
