Installing PHP w/oracle support on OSX

I'm trying to configure PHP to allow me to connect to an oracle database on another server (Linux). I am using an apple Xserve that uses OS X.3. When I use the '--with-oracle' option, it errors asking for the path to oracle on my Xserve (even though all I need it for is to connect to another server). I've been looking around for a version of oracle that would work on OS X so that I can configure my build of php to connect to this other server, but I haven't been able to find one. Does anyone know either what version of oracle I need to install to make php work using the '--with-oracle' option (and where I can get it), or does anyone know a better way of setting up php on OS X to connect to an oracle database on another server. Any help would be greatly appreciated. Thanks, Nathan Packard
