Bug#841885: gerris: autopkgtests fail with openmpi2

[Graham Inggs]

Source: gerris
Version: 20131206+dfsg-9

Hi Maintainer

Since the transition to openmpi2, gerris' autopkgtests have been
failing with the following error:

orte_ess_init failed
--> Returned value A system-required executable either could not be
found or was not executable by this user (-126) instead of
ORTE_SUCCESS

I solved this by adding mpi-default-bin to debian/tests/control as follows:

--- a/debian/tests/control
+++ b/debian/tests/control
@@ -1,2 +1,2 @@
 Tests: testHydro testKinetic testPlate testQuadr
-Depends: gerris, libgfs-dev, build-essential, pkg-config, mpi-default-dev
+Depends: gerris, libgfs-dev, build-essential, pkg-config,
mpi-default-dev, mpi-default-bin

However, if the dependencies libgfs-dev, build-essential, pkg-config,
mpi-default-dev and mpi-default-bin are actually needed for normal
usage of gerris, then maybe they should rather be added to the gerris
package's Depends in debian/control.

Graham
