This an odd one.
require 'rubygems'
works in my scripts . . . but if I go to IRB to test some 'rspec' stuff.
I get:
require 'rubygems'
=> false
Tried including the whole path, but that did not work either any ideas
why scripts being run don't have a problem requiring rubygems but IRB
does?

The value returned by require doesn't tell whether there was an error or not
(if the file can't be found, a LoadError exception will be raised). Rather,
since require tries to avoid loading a file more than one time, it says
whether you required the file for the first time (true) or if it had already
been loaded (in this case returns false and doesn't try to load the file
again). So, the fact that in irb
require 'rubygems'
returns false only means that the file rubygems.rb had already been loaded,
and it wasn't necessary to load it a second time.

When you get "false" it means that library was **already** loaded. Example:
~$ irb
irb(main):001:0> require 'time'
=> true
irb(main):002:0> require 'time'
=> false
If the library doesn't exist in the configured path you would get an error:
irb(main):001:0> require 'non_existing_library'
LoadError: no such file to load -- non_existing_library
from (irb):1:in `require'
from (irb):1

Hmmm . . . then I have a different problem.
on to requiring rspec

And this is the second time I have unistalled and re-installed rspec.
Tested other GEMs . . .
require 'snmp'

That's because rspec doesn't provide a rspec.rb file but a spec.rb file. So
require 'spec'
should work.
