I think that Ubuntu's packaged version of 'rubygems' (the one installed 
with Synaptics, Adept, or apg-get) is too old.  Remove the packaged 
version and install the latest rubygems from 
http://rubygems.org/read/chapter/3.

The other side-effect this has is that on Ubunty 7.04 and 7.10, the gem 
installation directory moves from /var/lib/gems/... to 
/usr/lib/ruby/gems/...  I reinstalled all my gems.  There may be a way 
to play with some environment variables, but it wasn't worth the trouble 
to me to keep something working that doesn't follow convention (it's not 
the Rails way).
