[mpich-discuss] "make testing" fails on machine?

[James]

Hi,

I'm having a strange problem with mpich.  I built & installed it on
machine A (a Lenovo T61 running OpenSuSE 13.1), and it seems to run
fine on that machine (using mpiexec to start multiple processes).
Now I built it on machines B & C (both Intel quad-core, one with
OpenSuSE 12.2, one with 13.1).  The code is from the same .tgz
file ( mpich-3.1.2.tgz) and configured the same (--prefix=/opt/mpich
   --disable-fortran), but 'make testing' fails with messages like
the following.  (But if I make e.g. the cpi example and run it as
a non-MPI program, it runs ok.)  As far as I can tell, the relevant
paths & environment vars are exactly the same on all three systems.

Any clues as to what my problem could be, or even where to start
looking?  I did try running mpiexec with the -verbose flag, but
none of the output seemed to make sense to me.
