Issue 1:
Hi! I'm using scipy version 0.18.1 under ubuntu, but when I run scipy.test() in the terminal, it raise the following error:

======================================================================
ERROR: test_fitpack.TestSplder.test_kink

I don't know how to fix it, can anyone help me? thanks very much!

Issue 2:
I've recently updated scipy in Fedora to newest 0.13.0 release and I can see one test failure on every architecture, both in python 2 and 3:

Python 3.3.2
