That warning isn't critical, and you should be able to receive packets anyway.

Run again with --log, and look at the outputted .dat files (either in  
octave with the instructions on the gnuradio website or using the  
provided gr_plot_const.py and friends) to see if they look remotely  
close to what you expect. (compare and contrast with the output of  
benchmark_loopback.py --log).
If nothing is being printed that's usually (for me, at least) a sign  
that the link between the two radios isn't good enough for anything to  
make it through.

What are the full command lines you're using for each (tx and rx)?
