It works fine if run manually in a iurt chroot, but was failing when
trying in a chroot without a tty (which will be the case during a
build), however the error was different:

--------------------------------------------------------------------------
mpirun was unable to launch the specified application as it
encountered an error:

Error: pipe function call failed when setting up I/O forwarding subsystem
Node: jonund.mageia.org

while attempting to start process rank 0.
