I recently blew away and re-installed rvm to fix some issues.
Now, however, when I try and install ruby-debug19 I get:
$ gem install ruby-debug19
... then ...
Building native extensions. This could take a while...
ERROR: Error installing ruby-debug19:

Could not create Makefile due to some reason, probably lack of necessary

need configuration options.

Gem files will remain installed in /Users/snowcrash/.rvm/gems/ruby-2.2.1/gems/linecache19-0.5.12 for inspection.

And the log just contains these lines.
Any suggestions?
