Mysql 5.5 + Rails 3: uninitialized constant Mysql::Error
I spent a few hours trying to track down this error before finally finding the problem. Googling around you see posts saying the fix is to uninstall and rebuild the mysql gem against your local install of mysql.
For me this did not fix my problem. I encountered the same error, but caused by installing Mysql 5.5 on a new OS X environment. Aparently, the current stable version for rails/osx development is Mysql 5.1.
If you have installed 5.5:
1) uninstall following these instructions.
2) Download MySQL 5.1 here and run through the install for db, preference panel, and startup item.
