Have you verified that that module is actually installed where you
think it is? If you are just building the gr-howto-write-a-block like
this:

cmake -DCMAKE_INSTALL_PREFIX=/opt/howto [path to source]/gr-howto-write-a-block
make && sudo make install

When you look in /opt/howto/lib/python2.7/dist-packages, you will find
a 'howto' directory. Under that, you'll find:

howto_swig.py
howto_swig.pyc
howto_swig.pyo
_howto_swig.so
__init__.py
__init__.pyc
__init__.pyo

All of those files have to be there. Then, if
PYTHONPATH=/opt/howto/lib/python2.7/dist-packages, you can 'import
howto' from inside Python.
