1.9, similar to how the lang/python ports are handled. ruby 1.8
now installs as ruby18 and ruby 1.9 installs as ruby19. The
included MESSAGE files for both ports let you know the symlinks to
set up if you want to make that version the default system ruby.
Split port originally started by bernd@, many changes since by me,
help and support from jcs@, landry@, jasper@, and sthen@.
This causes a large amount of fallout in dependent ruby ports,
which will be committed shortly.
OK jcs@, landry@, jasper@, sthen@
