After the 7.2 upgrade boost-openmpi-1.53.0-25 was installed, along with openmpi-1.10.0-10. The old openmpi was then replaced with compat- openmpi16-1.6.4-10. All fine.
Except boost-openmpi has a dependency on the old libmpi.so.1 and the new openmpi has libmpi.so.12:

We have tried switching to using compat-openmpi - but then the programs don't find the boost library.
There are other ways around it (setting the LD_LIBRARY_PATH variable or putting in symlinks so things are found), but they seem to throw segfaults with the code.
Presumably this is just a packaging/compiling error - is there anyway to trigger an update for the boost-openmpi package?
