The correct command is "sudo gcc_select mp-gcc45" which effectively does all the symbolic links for you and works like a charm, so please ignore my previous patch.
I am not a mac user, so I guess that my opinion is not very educated, but isn't your patch still useful: test if 'gcc' exists, and if not fallback to your patch, so that it still works for the clueless user?
Indeed, having scipy build out of the box would be nice, but it's not for me to decide if numpy.distutils should overcome these limitations in macports ... On the other hand, as installing on macports is not that trivial, I strongly feel that a subsection 'Macports' should be added to scipy's INSTALL.txt file, where it details needed packages, the gcc_select trick and options needed in site.cfg for umfpack. I'll gladly provide a patch for that if people are OK. Fabian.
My 2 cents,

I would prefer to just document the gcc_select solution, since it solves the problem at hand.

The most up-to-date instructions are at http://www.scipy.org/Installing_SciPy/Mac_OS_X, so those should be updated as well. That said, if a "Macports" section is added there should be a strong disclaimer that it is *not* the recommended way to install numpy/scipy. A good portion of the build problems reported on these lists are related to Fortran on OS X, and a specific gfortran build at http://r.research.att.com/tools/ is recommended for a reason. If a user really wants to use Macports some notes in the docs may help, but let's not give the impression that it's a good/default option for a new user. Cheers, Ralf
