Bug#865526: libpetsc3.7.5-dev: uninstallable on current sid

[Giacomo Mulas]

Package: libpetsc3.7.5-dev
Version: 3.7.5+dfsg1-4+b1
Severity: grave
Justification: renders package unusable

Dear Maintainer,

since openmpi was upgraded in sid, libpetsc3.7.5-dev and libpetsc3.7.6-dev
became uninstallable on sid, since they depend on libopenmpi-dev (< 2.0.3).
I tried compiling the package from source but it gets stuck precisely when
checking mpi. Upon further checking it looks like the openmpi development
environment on my laptop is broken, despite all packages appear to be
correctly installed: many libs are installed only under 
/usr/lib/x86_64-linux-gnu/openmpi/lib, with no soft links to 
/usr/lib/x86_64-linux-gnu (even if running dpkg -L libopenmpi2 says they
should be!).

Any chance to have petsc-dev installable again soon?  petsc and slepc are
key dependencies of my quite a bit of my home-developed scientific software. 
Any suggestion for a quick-n-dirty fix to get it to compile with the newer
openmpi?

Thanks in advance. I'll let you know if/when I can compile a working petsc
package from source.

Bye
Giacomo
