You may want to ask on the ruby list instead of the rubyonrails list...

Silly question: did you install nokogiri? That message above tells you
just what it cannot find.

Now try:

gem list | grep nokogiri

In looking at the rubyXL gem, the gemspec file does list nokogiri and a
few other things as run-time dependencies, but I don't quite understand
the syntax used in the .gemspec -- it *looks* like it should pull them
in, but neither gem install nor bundle install (if rubyXL is placed in a
Gemfile) are getting included.

If you look inside the rubyXL.gemspec file where rubyXL was installed,
you can find the other things it depends on and install those as well.
