Yes, you should be worried. To run the numpy tests you need to install nose. That's what your output said:
ImportError: Need nose >= 0.10.0 for tests - see http://somethingaboutorange.com/mrl/projects/nose
For h5py, you might want to try the h5py list. Did you remove the build directory? Because I don't know much about installation, I remove everything: the installed package, the build directory.
Thanks for the tip on nose. I installed it, and now I see that I have 5 numpy failures:
