Bug#887352: stretch-pu: package mpi4py/2.0.0-2.1+deb9u1

[Andreas Beckmann <anbe@debian.org>]

Package: release.debian.org
Severity: normal
Tags: stretch
User: release.debian.org@packages.debian.org
Usertags: pu

mpi4py contains a hardcoded list of libmpi sonames to dlopen(), this
does not include libmpi.so.20 as used in stretch. Therefore mpi4py
currentl only works if a mpi dev package providing the fallback
libmpi.so is also installed.
Add the current soname to the list s.t. mpi4py without changing the
dependencies. #860476
