Hi!

Thanks for the patch.

I have the following suggestions:

* Please unbundle volk.
* Please build the documentation (that needs doxygen, ghostscript and texlive-tiny).  After that, remove docs/doxygen/html/_formulas.log because it contains timestamps.
* Please add dependency to alsa-lib.
* Please add dependency to libusb.
* Why not fftwf?
* We should investigate whether grc actually needs the inputs to be propagated (later).
* Please add dependency to cppunit.
* Please add dependency to orc.
* Swig probably is not needed at runtime - isn't a native-input enough?
