Hi Sandro,

Yes, I see that the lines

ifeq (,$(findstring notest,$(DEB_BUILD_OPTIONS)))
         -for v in $(PYVERS) ; do \
                 python$$v -c "import sys ; sys.path.insert(0, '$(CURDIR)/debian/tmp/usr/lib/python$$v/dist-packages/') ; import numpy; numpy.test()" ; \
                 python$$v-dbg -c "import sys ; sys.path.insert(0, '$(CURDIR)/debian/tmp/usr/lib/python$$v/dist-packages/') ; import numpy; numpy.test()" ; \
         done
endif

are failing. Is that the problem?

I don't see why the trick here is failing. It looks like it should work. 
It does if I perform the tests manually. Ie. add the local path to 
sys.path first, and then import numpy, and run numpy.test().

To disable the tests, should I just comment out those lines, or should I 
set DEB_BUILD_OPTIONS, and if so where?

I'm not sure why the tests are run as part of the build anyway.
