The "official" pyhdf and this fork was released around the same time and have the same version number. Confusing! But I'll take your word that this one is better. I'd keep the fork comment in the description though, in case someone is looking for pyhdf. Could you wrap pyhdf in '@url{}'? Regarding the patch, I wonder if it should go in (gnu packages maths), similar to how we put PDF libraries in pdf.scm and XML in xml.scm etc. But no strong opinion here. 'python-numpy' should be a propagated-input since it is imported at runtime, and not a dynamically linked C library like the other inputs. The 'check' phase seems to run the build again, and prints at the end "Ran 0 tests in 0.000s". Looking at the Github ".travis.yml", the CI tool runs the command "nosetests" instead of 'python setup.py test' like python-build-system does by default. Can you try replacing the 'check' phase with that command? You'll need 'python-nose' as a native-input. It seems you also forgot to add a copyright line. Can you send an updated patch? Thank you! :-)
