The intention is to get a clean build of MRI 1.8.7 and 1.9.3.
MRI 1.8.7 doesn't play nicely with LLVM based GCC compilers. In Mountain Lion, the only way to get a non-LLVM gcc is to build one yourself. The command line tools package in Xcode 4.4 does not contain a non-llvm based GCC.
- Upgrade to Mountain Lion
- Remove all previous copies of Xcode

I say "animated gif" but in reality I think it's irresponsible to be serving "real" GIF files to people now. You should be serving gfy's, gifv's, webm, mp4s, whatever. They're a fraction of the filesize making it easier for you to deliver high fidelity, full color animation very quickly, especially on bad mobile connections. (But I suppose if you're just doing this for small audiences (like bug reporting), then LICEcap is a good solution).
- Launch quicktime player
- do Screen recording
