Doesn't

gem list

does what you want? On my system (with rubygems 1.3.1) this command prints a 
list of all the installed gems, together with their version. For example, a 
part of the list looks like this:

rdoc (2.2.1)
RedCloth (4.1.1)
rice (1.0.2)
rspec (1.1.12, 1.1.10)
ruby-debug (0.10.3)
ruby-debug-base (0.10.3, 0.10.2)
rubyforge (1.0.1)
RubyInline (3.8.1)
