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

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

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.
