Error installing ruby-debug

Say you do:

gem install ruby-debug

and get:

Error installing ruby-debug.

ERROR: Failed to build gem native extension.

Can’t handle 1.9.x yet

*** extconf.rb failed ***

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

libraries and/or headers. Check the mkmf.log file for more details. You may

need configuration options.

Here’s one solution:

1. make sure you reference the right ruby headers, e.g.

gem install ruby-debug19 — -with-ruby-include=$rvm_path/src/ruby-head/

(make sure you get the right number of hyphens!)
