MAMP by default doesn't allow TCP connections. You can either turn it on or use sockets.

Changing your dsn as @Tom suggests should fix your issues. Weird as it is but using localhost instead of 127.0.0.1 makes that mysql connects through sockets.

http://dev.mysql.com/doc/refman/5.0/en/connecting.html :

On Unix, MySQL programs treat the host name localhost specially, in a way that is likely different from what you expect compared to other network-based programs. For connections to localhost, MySQL programs attempt to connect to the local server by using a Unix socket file. This occurs even if a --port or -P option is given to specify a port number. To ensure that the client makes a TCP/IP connection to the local server, use --host or -h to specify a host name value of 127.0.0.1, or the IP address or name of the local server. You can also specify the connection protocol explicitly, even for localhost, by using the --protocol=TCP option.
