As the primary author of GetPrerequisites and BundleUtilities, I'm gonna
chime in here, even though I don't have time in the near term future to do
much useful work on the topic...

I think that the missing *.nib files should be accounted for by adding the
capability to BundleUtilities to copy *all* of the files in a copied
framework. Right now, it copies *only* the actual binary dylib files to
minimize the size of the resulting bundle. Clearly that does not work for
libraries that depend on embedded resources that are in other parts of the
framework. I would like, moving forward, to add the ability to say "copy
everything" or "copy this list of extra stuff" for any given framework that
gets pulled in because it is a prereq.

Hopefully, my expression of this intent will guide anybody else interested
in contributing a patch before I do have the time to get to it myself. :-)

If there is anybody out there who can spend the time on this right now, I'd
be happy to act as a reviewer or collaborator. Just ping me.


Thx,
David Cole
