OK, grabbed that (1.4a1r21825). Configured with:

./configure --prefix=$FOO --with-openib --with-tm=/usr/
local/torque/latest --enable-static --enable-shared

It built & installed OK, but when running a trivial example
with it I don't see evidence for that code getting called.
Perhaps I'm not passing the correct options ?

^Cmpiexec: killing job...

Increasing odls_base_verbose only seems to add the environment being
passed to the child processes. :-(

I'm pretty sure I've got the right code as ompi_info -a
reports the debug setting from the patch:

MCA odls: parameter "odls_base_report_bindings" (current value: <0>, data source: default value)

Great, anything I can help with then please let me know,
I'll be back from leave by then.

All the best,
Chris
