It can, and no change should be necessary.

The problem you are experiencing is an installation problem, not an
architectural problem. For some reason, the FPC application fails to
find the libraries. However, I have no idea why this happens.
I'm not a Mac OS X expert, so I can't help with that.
As far as the 'recommendation' is concerned: for systems with multiple
CPUs it is better to use Classic server, as Superserver can use only
1 processor. The upcoming version 2.5 of Firebird should remedy that.
