This seems to be correct.

Since some time I've pushed a 2to3 based port to Git.  I've now fixed
some issues of this and I wonder whether we might give it a try to do
the port inside Debian.  For the moment I'm running into the following
issue:

The problem is that the former build system using python2.7 and cython had created

  obitools: /usr/lib/python2.7/dist-packages/obitools/_obitools.x86_64-linux-gnu.so


But now with python3.7 and cython3 the result are single dynamic libs.
I'd love to give at least the test suite a try so if I get some hint how
to create that single _obitools.x86_64-linux-gnu.so instead of those
many *.so libs I could possibly run the test and see how it performs.

Kind regards

       Andreas.
