Comment (by uri@…):

 > Does swig-ruby work with both ruby (1.8) and ruby23 (2.3)?


 It should.


 > I'm hoping we can make this dependency change something like
 "path:bin/ruby:ruby" ... stick with the "ruby" port unless some other
 rubyXY port is already installed.


 This sounds like the right approach, IMHO.


 > After installing ruby and ruby23, I don't see a common file


 Not sure what you mean. Installing ruby or ruby23, you get
 /opt/local/bin/ruby (the main interpreter), and  bunch of libraries and
 supporting files. I don't think you can install them both at the same
 time.


 > Thus, we'll need to move to the +rubyXY variants, like what swig-php has


 I don't know if we need to go that way - but if we do, I see no problem.
 It's easy enough on the user.


 > Do you know enough about Portfile editing to create such a patch &
 verify that it works as expected?


 I can't claim this knowledge, but let me take a look...
