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 On Oct 12, 9:17 pm, Sam Esam <[email protected]> wrote: > Hi > >
