I was having the same problem on Snow Leopard and, after some time I did the following:  
Removed all mysql gems I had:  gem uninstall mysql  

In my case I had to specify both mysql-dir and mysql-config (and -arch x86_64 to 64 bits)  export ARCHFLAGS="-arch i386 -arch x86_64" ; 

gem install --no-rdoc -- no-ri mysql -- --with-mysql-dir=/usr/local --with-mysql-config=/usr/ local/mysql/bin/mysql_config  

Hope it works
