The old laptop is running OS X Lion 10.7.5. It has Python 2.7.1 and Python 3.3.0. It also has Ruby 1.8.7.
I seem to remember I had Ruby 1.9.2 installed in an Ubuntu VM. That VM is not running well. (Something happened in a recent update and I can’t get the updates installed.)
I will definitely need to install JewelryBox for multiple Ruby installs. If I can, I’ll also update Python to 3.3.5, if possible. I can see I already have too many projects running all at the same time. This is not good.
