I've a user who's trying to install my simple_ra code.  It builds just fine, but upon running, runs into a linker error involving VOLK:

raceback (most recent call last):
  File "/home/peter/bin/simple_ra_receiver.py", line 23, in <module>
    from grc_gnuradio import blks2 as grc_blks2

    _digital_swig = swig_import_helper()

    _mod = imp.load_module('_digital_swig', fp, pathname, description)
ImportError: /usr/local/lib/libgnuradio-digital- undefined symbol: volk_32f_binary_slicer_8i

This is a 32-bit install of Ubuntu 14.04, I don't know exactly what type of hardware.

I vaguely recall noise about 32-bit VOLK installs becoming confused, but I can't find that thread.

They installed using build-gnuradio, and that apparently worked just fine  (or, at least, didn't fail to the point that build-gnuradio noticed).
