     Type:  defect  |     Status:  new
 Priority:  Normal  |  Milestone:
Component:  ports   |    Version:  2.3.4
 Keywords:          |       Port:  swig-ruby
--------------------+--------------------------------
 swig-ruby requires ruby-1.8.7 instead of being able to use the current
 ruby-2.3 port.

 The Ruby level should either be the currently available version (2.3 for
 now), or an installation parameter.
