Hi,

during a test with piuparts I noticed your package fails to upgrade from
'sid' to 'experimental'.
It installed fine in 'sid', then the upgrade to 'experimental' fails
because it tries to overwrite other packages files without declaring a
Breaks+Replaces relation.

See policy 7.6 at
https://www.debian.org/doc/debian-policy/ch-relationships.html#s-replaces

>From the attached log (scroll to the bottom...):

  Selecting previously unselected package libopenmpi3:amd64.
  Preparing to unpack .../9-libopenmpi3_3.0.0-1_amd64.deb ...
  Unpacking libopenmpi3:amd64 (3.0.0-1) ...
  dpkg: error processing archive 
/tmp/apt-dpkg-install-EFFXvG/9-libopenmpi3_3.0.0-1_amd64.deb (--unpack):
   trying to overwrite '/usr/lib/x86_64-linux-gnu/libpmix.so.2', which is also 
in package libpmix2:amd64 2.0.1-1
  Errors were encountered while processing:
   /tmp/apt-dpkg-install-EFFXvG/9-libopenmpi3_3.0.0-1_amd64.deb

Given that libpmix.so.2 has SOVERSION 2, but all other libraries in
libopenmpi3 have SOVERSION 40, this should be in a separate package as in sid.


cheers,

Andreas
