I would put them in Frameworks too, myself, but I haven't used 
bundlebuilder enough to know that it knows how to put stuff other than 
the Python framework there.

Cool :)

I like to modify the references so it's more deterministic.. AFAIK dyld 
will always try the mach-o header references first, then start poking 
around at the search paths.  In my suggested case, it will link to the 
included binaries regardless of what the user has installed.

There is definitely a case for using potool to allow bundlebuilder to 
find these libraries for you (i.e. check references that don't live in 
/System or /usr/lib and move those frameworks and libraries into the 
bundle).

I also think that since some modules reference the same dynamic 
libraries, it might make sense to have an option to do even more 
relocation (in the case where they use different versions or 
something).. for example you could put things in 
@executable_path/../Frameworks/%s/ where %s is the name of the python 
package that depends on that dylib or framework.  I don't know of any 
real cases where a conflict of this nature happens, so it might be 
YAGNI.
