I'm copying your reply back to the list.  You'll get more and better
responses if you keep all of the discussion on there.

I don't see anything unusual going on there either.  I do see that the
project page for gen2_rfid is asking for a particular SVN revision of
gnuradio with custom edits applied.  Is that how you installed
gnuradio?  I'm looking at the notes in
https://www.cgran.org/browser/projects/gen2_rfid/trunk/README.txt and
https://www.noisebridge.net/wiki/RFID_Hacking/usrp/
