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

sudo gem install mysql -v 2.7 -- --with-mysql-config=/usr/local/mysql/bin/mysql_config also did the trick for me when migrating over to my new Snow Leopard laptop. I did not use MacPorts to install mysql, but rather the binary, and had no luck with the arch flag solutions or symlinks.
