Known Issues

Ruby

Rubies older than 1.9.3-p429 will not compile with Clang and require GCC >= 4.2. Normally, Linux and BSD systems will already have GCC installed. OS X users can install GCC via [homebrew]:

brew tap homebrew/versions
brew install gcc49

And run ruby-install again:

ruby-install ruby 2.4.0 -- CC=gcc-4.9

Rubinius

Rubinius 1.x and 2.0.x is not supported due to multiple bugs. Instead, please use Rubinius >= 2.1.x.
