Thanks all,
I went to http://numeric.scipy.org which led me to 
http://sourceforge.net/projects/numpy and installed NumPy.  I suppose I 
should read the README that comes with gnuradio when I go to a different 
version gnuradio. Eric Cottrell's usrp_oscope_ms.py seems to work now.  
I'll have to take a look at it since the default parameters give alot of 
USRP overruns.  Make check was successful besides the timeout problem 
with mblock.
