Thanks Eric,
I see what you are saying.  What I ended up doing to correct the error 
is svn'd your version of gnuradio:
svn co http://gnuradio.org/svn/gnuradio/branches/developers/wb1hbu/wip/ 
gnuradio.1
then: ./bootstrap, ./configure, make, make check, make install.
What does it take to keep a stable release of gnuradio and only add your 
piece of gr-air and have it all compile and install correctly?

Now when I run usrp_mode_s_logfile.py I get:

Traceback (most recent call last):
 File "./usrp_mode_s_logfile.py", line 3, in ?
   from gnuradio import gr, gru, usrp, optfir, eng_notation, blks, air
 File "/usr/local/lib/python2.4/site-packages/gnuradio/gr/__init__.py", 
line 27, in ?
   from gnuradio_swig_python import *

line 6, in ?
   import _gnuradio_swig_py_runtime
ImportError: libgromnithread.so: cannot open shared object file: No such 
file or directory

When I run a find on libgromnithread.so I get:
/usr/local/lib/libgromnithread.so
/home/towens/gnuradio.1/omnithread/.libs/libgromnithread.so

I did see a make check error that showed error on check_TESTS 
/gnuradio.1/gnuradio-core/src/python/gnuradio/gr, check_am, and 
check_recursive

Thanks for your help,

Tom
