We have made gnuradio build with a private copy of libusb-0.12 and it is 
staically linked against this copy. Further clubbing was needed to stop 
libtool trying to link apps that used the USRP from linking to the library.

I think there are only a small handful of apps that do not use the 
public libusb interface.

Do you have a specific package you are having issues with? Take a look 
at the gnuradio.inc file to see how we solved the problem there.

PS: By solved I mean it builds, I had to leave for Linuxtag before I 
could test extensively :)
