Missing Ruby Console Menu Item on Mac OS X

When I started SU on my Macbook, the expected "Ruby Console" menu item did not appear at all in the Tools menu.

I figured out why, and I thought I'd share it here in case it saves others from similar frustration.

The problem is that the installed resources and ruby files have capitalization that is different from what the installed ruby scripts use. For example, sketchup.rb looks for "gettingstarted.strings", but units.rb (and others)

look for "GettingStarted.strings". If you chose, as I did, to install OS X on a case-sensitive filesystem, this won't work.

A workaround is to patch up all of these ruby files to use the names with the correct capitalization. Change those and the Ruby Console will work again.
