Here's the command I used for installing for development purposes --

CC=gcc-4.7 RUBY_CONFIGURE_OPTS="--with-openssl-dir=`brew --prefix openssl` --with-readline-dir=`brew --prefix readline` --with-gcc=gcc-4.7 --enable-shared" rbenv install --keep 2.0.0-p195

The -k is for --keep, which I seem to need since I'm developing Ruby C extensions.

I also found it necessary to use CC=gcc-4.7 because otherwise it would ALWAYS insist upon appending this Wshorten-64-to-32 flag, no matter which compiler I was using to build extensions. --with-gcc=gcc-4.7 is insufficient.

Note: This also seems to work with later GCC versions. I've tested with 4.8 and 4.9 also, but it's been a while.
