commit f1bd2577bde84232bd9c04134e485ae0223ab54d
Author: Drew Parsons <dparsons at debian.org>
Date:   Mon Apr 4 23:23:17 2016 +0800

    ensure deprecated alternative libpetsc.so.multiarch is removed
    
    if libpetsc.so.multiarch is still in use then remove all petsc
    alternatives (both real and complex).
    
    Use Conflicts: to ensure older versions of libpetsc3.6.3-dev,
    (and libpetsc3.6.2-dev), real and complex, do not remain installed.
