Finally got my E320 in and I cross-compiled a new setup.  I tried to fire up my 
flowgraph (which works fine on an E310) and it is complaining about numpy 
missing.

If I do a search from / on the E320, the only numpy that is showing up is:
/usr/include/boost/python/numpy

If I do a search from a good E310 in / I see:
./usr/lib/python2.7/site-packages/numpy
./usr/lib/python2.7/site-packages/numpy/core/include/numpy
./usr/lib/python2.7/site-packages/Cython/Includes/numpy
./usr/include/boost/python/numpy


Back on the host machine, my E320 cross-compile prefix shows numpy:
./sysroots/cortexa9hf-neon-oe-linux-gnueabi/usr/include/boost/python/numpy

My good E310 prefix shows:
./sysroots/armv7ahf-neon-oe-linux-gnueabi/usr/src/debug/python-numpy/1.13.1-r0/numpy-1.13.1/build/src.linux-x86_64-2.7/numpy
./sysroots/armv7ahf-neon-oe-linux-gnueabi/usr/src/debug/python-numpy/1.13.1-r0/numpy-1.13.1/build/src.linux-x86_64-2.7/numpy/core/include/numpy
./sysroots/armv7ahf-neon-oe-linux-gnueabi/usr/src/debug/python-numpy/1.13.1-r0/numpy-1.13.1/numpy
./sysroots/armv7ahf-neon-oe-linux-gnueabi/usr/src/debug/python-numpy/1.13.1-r0/numpy-1.13.1/numpy/core/include/numpy
./sysroots/armv7ahf-neon-oe-linux-gnueabi/usr/lib/python2.7/site-packages/Cython/Includes/numpy
./sysroots/armv7ahf-neon-oe-linux-gnueabi/usr/lib/python2.7/site-packages/numpy
./sysroots/armv7ahf-neon-oe-linux-gnueabi/usr/lib/python2.7/site-packages/numpy/core/include/numpy
./sysroots/armv7ahf-neon-oe-linux-gnueabi/usr/include/boost/python/numpy

So, was numpy forgotten?  Left out for a reason?  I am going to attempt to 
build it by hand, but I have a fear that I am going to go down dependency hell 
with this and other missing packages that GR might want.
