I took Dan Halperin's advice and totally deleted my build tree- I also
totally cleaned out all traces of gnuradio and re-checked out everything
from subversion and re-built (n4hy's tree) and am still missing

As you may have seen from my first post in this thread, I was originally
getting an error about _Z15gr_make_fft_vccibSt6vectorIfSaIfEE being missing
using the n4hy's benchmark_ofdm_tx on after make installing n4hy's tree over
the stable..- and after make uninstalling the stable tree, and make
installing n4hy's, I now am missing the swig python bit.

So- I'm going to go and clean out everything again and rebuild the stable
tree and see if I get my swig_python bits back. Am I making a rookie mistake
here somewhere?
