It turns out that Ubuntu needed some ruby libraries installed - 
libzlib-ruby I believe.  Would there be a way to have RubyGems report 
when it fails a dependency requirement for itself?  Instead of 
`require': No such file to load -- rubygems/builder (LoadError)", 
something about zlib would be more helpful.
