Hello. I created a ruby program in Smultron, but I couldn't figure out
how to run it on a mac. Should I download anything to execute it? I
thought Macs had ruby pre -installed. Thanks.

You can also add the following line at the very beginning of your ruby
script:

#!/usr/bin/env ruby

and then run the following command in the Terminal.app:

chmod u+x /path/to/your/file.rb

Then you'll be able to invoke the file by its name.

By the way, ruby that comes with OS X is a bit outdated, so it will be
not a bad option to install a fresh version. The simplest approach is
to use MacPorts.
