I know I'm a little late to this party, but I thought I'd point this out: the output "VOLK: Error allocating memory (posix_memalign: 22)" suggests you are running into this known issue: http://gnuradio.org/redmine/issues/692
If this is indeed a rPi Rev B, then this is the known/old issue of volk_get_alignment() returning a value on 1 on that arch, which then breaks posix_memalign. I believe this has been fixed in more recent releases, so perhaps jessie-backports can help you there?
