FreeBSD port for RubyTk

[Nicola Mingotti]

I prepared the FreeBSD port for gem 'tk' .

I don't know if it will be accepted and how long it will take
to see it in the ports tree. So, you can find it here attached in case
you want to try.

The port compiles against Tk8.6 and installs it if it is
not already present in the system.
