Brandon I don't know what you really want to do, but what you SAID will not work (it may work in a trivial case).
If you want to build rpm for xxx distro eg CentOS5 then you need to build on CentOS5. I have examples where rpm built on COS6 won't work on COS5 machines never mind the foibles of OSX.
VBOX works nicely on mac and I have guests to build rpm for RedHat 9, COS5 and COS6 in 32 and 64 bit mode.

Save yourself the heart ache and believe that you cannot cross build rpm. ('course you can, but you really have to be on the ball to do that). Much much easier to install and use vbox
