Bug#1041480: python3-h5py: I can't use the debian provided python3-h5py as a dependency in my package because it is called h5py.-debian-h5py-serial

[Tim Molteno]

Package: python3-h5py
Version: 3.7.0-8
Severity: important

Dear Maintainer,

I am developing a package that depends on h5py. It is predominantly used on raspberry pi, and other single board computers. When I specify 'h5py' 
as a dependency, it does not pick up the system installed version. I think this is because it is named 'h5py.-debian-h5py-serial'. This causes
huge problems because the attempt to build takes more than an hour and then fails on an rPi3.

How should packages that wish to the debian python3-h5py as a dependency specify this.
