This script installs a patched version of ruby 1.9.3-p125 with patches to make ruby-debug work again (#47) and boot-time performance improvements (#66 and #68), and runtime performance improvements (#83 and #84).
It works with Xcode 4.3 and the clang compiler it ships with its command line tools package.
Huge thanks to funny-falcon for the performance patches.

Putting the following in your shell config (eg. ~/.bash_profile
) will make Rails even faster, but will increase its memory footprint:
export RUBY_HEAP_MIN_SLOTS=1000000
export RUBY_HEAP_SLOTS_INCREMENT=1000000
export RUBY_HEAP_SLOTS_GROWTH_FACTOR=1
export RUBY_GC_MALLOC_LIMIT=1000000000
export RUBY_HEAP_FREE_MIN=500000
