How to install mod_wsgi on Mountain Lion

There are apparently changes Apple made in XCode between Lion and Mountain Lion that cause the standard install method to fail. The conventional fix that comes up most often in a Google search at the time of this writing is to create a symlink between the new name of a Toolchain folder and the old name that the installer is supposedly looking for, like this 

sudo ln -s /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/ /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.8.xctoolchain 

I did this and tried to make mod_wsgi using Homebrew but it throws a cryptic apxs error. Long story short, I eventually compiled mod_wsgi from source myself, but it continued to through various errors, even though things seemed to be configured properly. I went back to a different Mountain Lion machine I had configured earlier using MacPorts. When I did that machine, I had no problems with mod_wsgi or the need for this toolchain symlink. Examining the Portfile for mod_wsgi gives the key. The missing element is adding the --disable-framework flag to the config file. After that, everything works fine. 

This flag should be added to the Homebrew Formula for mod_wsgi. I have never made a Formula before, but maybe one day I will do it. Below is the Gist showing what I did and how it worked.
