I want to be rid of 1.8.7's gemset called 'sam', so...
ruby-1.9.2-p0@chrislerum ~ 
rvm gemset delete 1.8.7-p302@sam
info: /Users/chris/.rvm/gems/[email protected]@sam already does not exist.

Question is, didn't this work before? Or is this not intended usage - should I first rvm switch to that 1.8.7 ruby, then try to delete that gemset?
