Some gnuradio python blocks need python-numpy to be present. Without
python-numpy, gnuradio-python based apps fails, on runtime, with
traceback like:

Traceback (most recent call last):
  File "./top_block.py", line 18, in <module>
    from gnuradio import analog

ImportError: No module named numpy
