Fixed it!
The answer was actually on one of the links I posted above. Before installing a version of ruby (rvm install 1.8.7) I needed to run "export CC=/usr/bin/gcc-4.2". With that in place, everything ran smoothly.
If you don't want to have CC permanently exported, you can do CC=/usr/bin/gcc-4.2 rvm install 1.8.7
