@swrobel are you able to compile rbx-2.3.0 manually or does it only fail to build under ruby-install?

@swrobel @spastorino why isn't `llvm-config` symlinked into `/usr/local/bin`? Ideally, homebrew should symlink all binaries.

@tastycode does `brew link llvm --force` also fix the issue with ruby-install (not to be confused with `rvm install`).

@SixArm :+1: for trying to fix this as close as possible to the root. The root being homebrew, imho.

Try `ruby-install --latest ruby` which should auto-update the versions/checksums. I plan on adding an `--update` or `--sync` option that's a little more explicit.

`--latest` (soon to be renamed to `--update`) simply updates the `stable.txt` version file (which lists the current stable versions which are available) and `versions.txt` (which lists all known versions), and...

Going to update the README to this: ``` List supported Rubies and their current stable versions: $ ruby-install Updates then list the supported Rubies and their current stable versions: $...

`~/.rubies//` seems a little too bespoke, and would cause issues with listing rubies from the directory; all other ruby switchers would need to filter out known architectures or having some...

Finally got around to adding support for the `RUBY_INSTALL_SRC_DIR` and `RUBY_INSTALL_RUBIES_DIR` env variables. Will be released in version 0.9.0. 43e837b3dff60163b21b70dd3262fbd6e0f7f147
