I have rubygems installed because the first thing I do after installing Ruby
1.9 is to run gem update --system, which updates gems to 1.3.5.   I had
forgotten that that just turns around and installs rubygems-update - so I
actually did use rubygems-update.
So, this is a problem for anyone who wants ruby 1.9 plus gems 1.3.5.
 Reverting to gems 1.3.1 "fixes" it:
$ rm -r
/Users/rsanheim/.rvm/ruby-1.9.1-p243/lib/ruby/site_ruby/1.9.1/rubygem*
$ gem -v
1.3.1
$ ruby -rubygems -rrubygems/specification -e 'gem "hoe"; require "hoe"; puts
"hi"'
hi
$ gem update --system

"hi"'
WARNING:  #<NoMethodError: undefined method `>' for nil:NilClass>

# same error, produces error log of every gemspec installed

Besides, I've seen this on other developer's machines, so its clearly not a
'just on my box' bug.
