That makes sense form a security point of view. Unfortunately, it means that each time a new version of PHP appears, one must edit my.cnf to change the target of the socket directive.

(Or does the MacPorts port of mysql take care of that automatically somehow?  I'm using the native binary installation of MySQL because I could never get the MacPorts version to work -- as I recall, because of difficulties of using a non-default location for the data directory.)
