JRuby is hardcoded to use '-mmacos-version-min=10.4' which is not compatible
with '-rpath' being used

I installed JRuby 1.6.5 using rvm and then tried to do 'gem install mysql2'.
Unfortunately as I'm running an up-to-date XCode the native extension cannot be
built because of '-rpath' being used. The full output is included after this
description.
The problem is due to '-mmacos-version-min=10.4' being set in the JRuby source
code. I've forked the git repo and submitted a pull request
(https://github.com/jruby/jruby/pull/98) that simply updates the value of this
to 10.5. I have compiled JRuby using this change and managed to install the
mysql2 gem with it. It might not be the ideal solution but it certainly solves
this problem.
The full error from 'gem install mysql2':
Building native extensions. This could take a while...
ERROR: Error installing mysql2:
ERROR: Failed to build gem native extension.
