Brice,
unless you want to enable/disable nvml at runtime, and assuming we do
not need nvml in Open MPI,
and IMHO, the easiest workaround is to update
https://github.com/open-mpi/ompi/blob/master/opal/mca/hwloc/hwloc1113/configure.m4
and add the oneliner
enable_nvml=no
a better option cou
FWIW, I am still open to implementing something to workaround this in hwloc.
Could be shell variable such as HWLOC_DISABLE_NVML=yes for all our major
configured dependencies.

Justin,
iirc, NVML is only used by hwloc (e.g. not by CUDA) and there is no real
benefit for having that.
as a workaround, you can
export enable_nvml=no
and then configure && make install

After looking into this a bit more it appears that the issue is I am building
on a head node which does not have the driver installed. Building on back node
resolves this issue. In CUDA 8.0 the NVML stubs can be found in the toolkit at
the following path: ${CUDA_HOME}/lib64/stubs
For 8.0 I'd
