shell scripts not linking to bin directory

[agoddard]

It looks like we're only linking *.rb executables. Would it be a good idea to also link the .sh versions of plugins here, or are there reasons we'd rather avoid this? https://github.com/sensu-plugins/sensu-plugins-cpu-checks/blob/master/sensu-plugins-cpu-checks.gemspec#L15

Hey @agoddard, the issue is that rubygems can't create binstubs for non-ruby files. To get around this we've added ruby wrapper scripts that execute the non-ruby files (see https://github.com/sensu-plugins/sensu-plugins-memory-checks/blob/master/bin/check-swap.rb for an example). We could do that here except there's already a check-ruby.rb so we'd need to call it something else.
