Hi All,

Apologies up front but I am a total newbie to Ruby and just starting out

I am on a Mac, snow leopard 10.6.8 and have pre-installed Ruby 1.8.7.

I am trying to launch IRB and getting the following, not sure how to
install IRB or if I have to do a complete install from source, any help
is appreciated. My book says I should see something like the following
