[Wheel-builders] Error from numpy wheel - any thoughts

[Matthew Brett]

I'm installing a manylinux wheel on a Debian sid machine I have.  For
the manylinux wheel, but not a local build, I get the following error
from `nosetests numpy.f2py`:

```
======================================================================
ERROR: test_kind.TestKind.test_all

```

Anyone out there with insight as to what's going on?

Cheers,
