[Hawkular-dev] HawkFX on Mac OS X issues?

Hi, I'm trying to use HawkFX on Mac OS X - I have it working great on Fedora but would like to set it up on my Mac OS X box as well. I've got no experience with ruby or jruby so I may be doing something wrong here in installation, because I'm seeing the following : lilguylaptop:hawkfx cunningt$ jruby -S -G hawkfx.rb NameError: uninitialized constant G Did you mean? GC const_missing at org/jruby/RubyModule.java:3348 <main> at -G: I installed rvm through homebrew and followed the current instructions in the README.adoc. Should I be installing from source using a tool other than homebrew to install rvm? It looks like I'm using rvm 1.28.0 and jruby 9.1.5.0. Does that seem right? Other possibly useful info : Mac OS X 10.12 java 1.8.0_31
