You are not supposed to install the OEM software that came with your MBP into any other computer.
However sometimes it is
possible, have you tried those DVDs that came with the MBP? If you already tried, then it's not that easy.
Maybe using Pacifist though, nice software.
Now to think of it, probably the software on your MBP discs is Intel only, so you won't be able to put it on the PowerMac, or maybe they are Universal Binaries ... if only my MBP would arrive ...
