It works for me.  

I strongly suggest that you NOT start copying stuff around by hand.
That will lead to (serious) confusion.  The .so file is the shared
library that contains part of the "glue" between your C++ code and
python.  The glue actually consists of two parts, howto.py and
_howto.so.  For more information on how this works, see the docs at
http://www.swig.org


Try importing the file from somewhere out of the build tree.

E.g., 

  $ cd /tmp
  $ python
  >>> from gnuradio import howto
