You can build from source on the Beagle. I have done it. However, the
Beagle has only a single core processor, you will have to mount swap
space, the 4G of memory isn't roomy - at all, and you will have to
install a bunch of additional packages. 

I don't recommend native builds but it can be done. Cross develop if
you can. I seem to recall it took a few /days/ to build, multiply if
there is a failure. You should also mount an external USB disk for
swap, /tmp, etc. 

The compiler on the Beagle is old. I installed a more modern version.

The Beagle isn't suited for GNURadio unless you have a low data rate
and low memory requirements, but it can work.

Regarding VOLK, you may have to tune the build. You will have to look
up the processor specifics and tune the build appropriately.
