gem compile nokogiri-1.5.2.gem does not produce a valid gem.

[skull-squadron]

The following doesn't seem to include binary extensions (ext/nokogiri/nokogiri.bundle):

rvm gemset create gem-compile-example1
rvm gemset use gem-compile-example1
gem install rake gem-compile bundler
curl -LO http://rubygems.org/downloads/nokogiri-1.5.2.gem
gem compile nokogiri-1.5.2.gem

Does gem install --development -l ./nokogiri-1.5.2.gem need to be called perhaps?

Update: gem install --development nokogiri does not work because this is not how the Nokogiri development environment is created.
