The RUBY license covers only the second portion of the license. It should not
cover the dual license portion. This will be covered by the port.
Discussed with: sunpoet
Templates, Mk/ lang/ruby*: add the RUBY license
The current Ruby license is an optional choice of BSD-2-Clause and the 'Ruby'
license. This is not OSI approved.
