They used libusrp, a proprietary driver that came with GNU Radio.
Now, there's UHD, which is independent, and GNU Radio has wrappers for
UHD.

If you're using the current master, don't worry. You can simply use UHD
with GRC provided everything's installed correctly (when you run
./configure, it lists the modules which will be installed and UHD should
be one of them).

I recommend ignoring anything non-UHD. Just make sure it's all
installed, fire up GRC (or Python) and start hacking.

Cheers,
