many hacks might be left overs for historical (age of the package)
+ backports (hence cythonize rule, allows to provide backports for older
debian/ubuntu via neurodebian) reason.  Would be nice to review/remove
those no longer needed, but attention should be taken care not to break
backportability. So far built/tested fine even for jessie (8) and ubuntu
xenial (16.04).

overall, as I've just noted in the bugreport, I think it is better to
concentrate on making upcoming 0.20 (will use pytest not nose among
other things) into debian.  

Outstanding few issues so far are reported/dealt with upstream:

updating packaging is in debian-0.20 branch at
