I have a handle on the PYTHONPATH now after finding it in a README. It is now 
set to /usr/local/lib/python2.3/site-packages and the gnuradio directory can 
be found.

This gets me back to the original usrp issue which is that although the 
usrp_interface.ihx and usrp_fpga.rbf files are being loaded and I can control 
LED1, I cannot yet run ./test_fusb.

This program errors out within usrp_prims.cc:usrp_open_interface. The routine 
_usrp_hw_rev is returning 2 for the new usrp hardware. I originally thought I 
was caught in a logic trap where the software might be looking for a hardware 
rev of 1 instead of 2, but that doesnt seem to be the case.

Rather, it looks like the external call to usb_set_configuration() is 
returning -1 and that brings the train to a halt.

I can now run some of the python test programs in gr_usrp to essentially the 
same place. They either error on opening the tx interface or the rx 
interface, whichever one occurs first in the source code.

At this point, I'm going to go have a beer, kick the dog, throw windows tomes 
around the room and then watch "I Love Lucy" on the telly.
