mysql5 problem?

When using the mysql5 +server port, I can't connect locally to mysql using localhost (root). Only 127.0.0.1 and the unix socket works. Any ideas how to fix? A lot of people have this problem on other platforms, as seen here in the comments section here: http://dev.mysql.com/doc/refman/5.0/en/can-not-connect-to-server.html However, none of those suggested fixed worked. I even tried removing the Unix socket line from the port file to see if that worked, but it did not. Any help would be appreciated. Thanks, Karl
