[Pythonmac-SIG] py2app/macho_standalone problem

[Kevin Walzer]

I'm having a problem with the macho_standalone component of py2app (I'm 
trying to use it, as the documentation says I can, to create a 
standalone app bundle of a non-Python application). Here is the output:

Kevin-Walzers-Computer:~ kevin$ macho_standalone ~/Desktop/AquaEthereal.app

struct.error: unpack str size does not match format
Kevin-Walzers-Computer:~ kevin$

What happens is that a few libraries get copied over to /Frameworks in 
my app bundle, then the process stops (there are lot of libraries to copy).

I'm not trying to create a universal binary, so I'm not sure what the 
error is. Is there a flag I can set so that it doesn't try to create a 
universal binary, i.e. macho_standalone Foo.app -arch ppc?
