ruby 2.0 (macports) supported by RubyMine 5+ ?
Selecting new ruby2.0 binary through 'Add SDK...' action is improperly detecting that rubygems are not installed.

Answer to self -
Use macport 'ruby_select' tool to select wanted/active ruby version.
Not sure when this dependency was added.
Solution:
$> sudo /opt/local/bin/port select ruby ruby20
Selecting 'ruby20' for 'ruby' succeeded. 'ruby20' is now active.
$> sudo /opt/local/bin/port select --list ruby
Available versions for ruby:
none
ruby18
ruby19
ruby20 (active)
