This is the recommended route on OSX. There are some notes in the 
README.txt in the root of the OSG distribution on OSX that outline many 
of the steps you list below.

There is documentation, but it is true that much of it is old. I haven't

This is probably true. The install script probably needs work.

I recommend downloading the OSX GUI cmake tool from the cmake website to 
do the configuration.
