Do you have more than one ruby installation?  I've got three (the system 
1.9, the system 1.8, and my custom 1.9 install which is more recent).  
Each install has it's own copy of the gem program, and if I install a 
gem with one in one version, the other versions have no idea that it's 
there.

Try:
which gem  (using the exact same form that you used for the gem install)
and also:
which ruby (again, using the same form that you used to attempt execution)

One of my installs is in /usr/local/bin/gem and /usr/local/bin/ruby,
another is in /usr/bin/gem1.9.1 and /usr/bin/ruby1.9.1,
the third is /usr/bin/ruby1.8 (gem isn't installed for that one),

Re: Debugging failed Ruby Gem require

Hi both,

thanks for the replies.  Updating the gem version and re-installing has 
fixed the issue.

Many thanks.
