Can Apache projects have external dependencies on Ruby licensed works?
A project written primarily and obviously in Ruby can have a dependency either on Matz's Ruby Interpreter (MRI), or on any Gem which is licensed under the Ruby license. Of course Gems written under other licenses (such as MIT) may also be OK, depending on the license.
