I've been working on an application bundle for MacOS X.

At the moment, it only runs on X86_64 based Macs.

The two big problems I see with it are (1) it isn't an Universal app, (2) 
everything is built with gcc 4.5.  Which means I must include gcc 4.5 and a lot 
of other stuff in the bundle in order to support compiling mex-files and 
oct-files.  I suspect both of these problems can be solved if the Xcode 
compilers are used with the gfortran patch provided by ATT Research.

I often given some thought to how I might use that combination with Macports 
(I'd have to edit several port files), or setup a MacOS X guest in VBOX and use 
Homebrew (which uses the gfortran patch) in order to create a bundle that plays 
nice with Xcode.  My main hesitation is "time" and "will it work"?

Have you tried building everything using only Xcode with the gfortran patch 
provided by ATT Research?
