That usually means that it couldn't load the mysql C extension. I'd
double check that the gem was installed in the right install of ruby
(there's another one that is part of Mac OS X itself). Also work
opening an irb console and requiring the mysql gem, see if you get a
more explicit error message or warning in the console logs.
