Also, using the Macports approach you'd need different Mac's to create the different bundles for different versions of MacOSX. When I began working on a bundle using Macports, I expected it would be straight forward, but it turned out to be clumsy and unreliable.

Even if we use MXE, it will require us to install XCode4 and Macports first to get all the basic GNU tools required to natively compile Octave. AFAIK to install the required tools, one needs to do something like

    sudo port install coreutils autoconf automake ...

I think the starting point for MXE is: a compiler, a shell and (GNU) make. Getting those installed on your system is out of the scope of MXE.

It took me some time to get access to Mac. Sorry for that. On Mac OS X I have set up my development environment. Cross-compilation of Octave works, but I still haven't been able to figure out how to get initial support for natively compiling Octave in Mac OS X. Can you provide some guidelines on how to do this since you have added native MSVC compilation in MXE?

./usr/bin/config.guess gives the output x86_64-apple-darwin12.2.1

So in Makefile the following must be done:
 
TARGET := x86_64-apple-darwin12.2.1
MXE_NATIVE_BUILD := yes

What should be the value of MXE_SYSTEM ?
