uninitialized constant MysqlCompat::MysqlRes (using mms2r gem)

Question

moved a rails app of mine onto a new server and had to install a few gem dependencies. However, after installing the mysql gem I get the error, uninitialized constant Mysql

Answer 1

I had the same problem after upgrading from Fedora 10 to Fedora 12. I fixed it by just uninstalling mysql gem and installing it again. So it complies with the new version of MySQL.
