I have never seen RVM instructions that include "gem install rvm". The instructions from the RVM site itself are:
To install and/or update the latest code from the github repository ( requires git ):$ bash < <( curl http://rvm.beginrescueend.com/releases/rvm-install-head )
I think that only people who are already familiar with Ruby and RubyGems will assume that the way to install RVM is with "gem install rvm", but when you think about it, that doesn't make much sense as RVM should manage your Ruby and Gem environments, not be installed within them.
