You can test building it on a mac using the sourceforge compile farm.
They have two macos-X machines (and lots of other architectures)
http://sourceforge.net/docs/E02/en/#top

I have been doing some tests on the sourceforge compile farm to see if we can 
use it for automatic build testing for gnuradio and usrp.
(You have to setup all your required libs in your homedirectory.
I have succefully build the usrp driver code on their debian-linux X86 machine.)

Since this is a remote machine, you can't hear anything of couse ;-)
