For some reason I just can't let this one go :D
I've updated the script at
http://gist.github.com/34621, it now successfully builds a completely static RMagick with zero external dependencies! Intel only though, I just don't understand the errors I get from libtool when trying to do a universal build. Includes the freetype, jpeg and png libraries, wouldn't be too hard to add tiff, etc. It would rock if somebody with better skills than I could get this building universal.
Oh yeah, you might have to add extra --without flags to the `configure` command for ImageMagick to avoid pulling in shared libs, for instance I have graphviz installed in /usr/local so I had to add --without-gvc to avoid a dependency on that shared library.
