+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
+    EOS
   end
