How to get ri working for ruby19?

[Carl Johnson]

I have ruby installed, but I can't use ri to access any documentation
for the base ruby.  The ri does show documentation for installed
rubygems, including ones installed from packages.  Does anybody know how
to get ri working, or should I submit a PR?

I had been using the package for ruby, but I just installed the latest
from the port and enabled rdoc, and it still doesn't work.  I have
updated the base system, ports, and packages today, so the base system
is FreeBSD 10.0-RELEASE-p6 and ruby is ruby-1.9.3.484_2,1.

Thanks for any suggestions.
