Bug#998215: h5py: FTBFS without network access

[Graham Inggs]

Source: h5py
Version: 3.3.0-3
Severity: serious
Tags: ftbfs

Hi Maintainer

As can be seen on reproducible builds [1], h5py FTBFS without network
access during one of its tests.  I've copied what I hope is the
relevant part of the log below.

Regards
Graham
