Consider using RVM or Cider to manage Ruby environments:

By default we don't compile REE as a shared library. From their documentation:
Please note that enabling --enable-shared will make the Ruby interpreter
about 20% slower.

For desktop environments (particularly ones requiring RubyCocoa) this is
acceptable and even desirable.

If you need REE to be compiled as a shared library, you can re-compile like so:
brew install ruby-enterprise-edition --force --enable-shared
