Pik Install Ruby Yields: Error: Private method 'gsub' called for nil:NilClass

[Josh Jacobson]

I just installed pik, and when trying:

 pik install ruby 1.9.3-p193

I received the error:

There was an error.
 Error: private method 'gsub' called for nil:NilClass

in: pik/commands/install_command.rb:24:in 'execute'
in: pik_runner:33

Thanks, suggestions?
