ZZ_pE.h is included via ntl_wrap.h

If you look at the g++ command
g++ -o src/ntl_wrap.os -c -fPIC -I/opt/sage/local/include -I/opt/sage/
local/include/python2.5 -I/opt/sage/local/include/NTL -Iinclude src/
ntl_wrap.cpp
it includes "-Iinclude" where ntl_wrap.h should be. Maybe this is a
scons issues and we should include
-I$SAGE_ROOT/devel/sage/c_lib/include
On a side node: ntl_wrap.cpp includes a couple NTL headers directly.
Maybe those should move to ntl_wrap.h
