Those who need alternative build chains can locate the path to the
correct numpy headers via

        python -c 'import numpy, os; print(os.path.dirname(numpy.__file__))+"/core/include"'

which is simple to pop in e.g. in a Makefile.

I think this is a price worth paying for supporting multiple versions,
and is in any case required on non-Ubuntu platforms.
