DOH!! As soon as I hit send, I realized I could try one more thing:

  x = $!

That gave me the error message. And then a key word popped into my head. 
I wanted the "stack trace." More googling gave me the .backtrace method.

So now I have:

begin
  puts "hello"
  bogus_command
rescue=> err
  x = "#{err.backtrace[0] #{err}}"
end

This works perfectly. So, unless there's A Better Way someone wants to 
suggest, I think I am good.

thanks for listening :-)
