The problem is that you installed mysql extension using ruby
"setup.rb" instead of the gem.

Please remove the site_ruby mysql.bundle file and try installing the
gem

if you do "gem which mysql" you will see that the entry point (the
library) is mysql.rb, not mysql.bundle in mysql gem version 2.8.1
