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 EOS end end
