Thanks guys for replying.

The reason I'm using the ". /usr/local/bin/irb" is because I have 
another company version of irb/ruby in /opt/third-party/bin/ and they 
have removed the 'gem' command.  So I cannot install new features and 
play with Ruby.

And if you look at the commands it is using the wrong irb i.e. the one 
in /opt/third-party/bin/ which doesn't have the gem command and not the 
one I just installed.  I hope this explains my predicament more clearly.
