slurm-libpmi is missing

[yellowhat]

Hi all,
I am trying to install openmpi with slurm support on cyclecloud:

spack install hpl^openmpi+pmi schedulers=slurm

But I get this error:

'/configure' '--prefix=/mnt/exports/shared/bin/spack/opt/spack/linux-centos7-broadwell/gcc-8.3.1/openmpi-3.1.5-3uku7u7irjzvpxy5uwajd34ksg5vyyim' '--enable-shared' '--with-wrapper-ldflags=' '--with-pmi=/usr' '--enable-static' '--enable-mpi-cxx' '--with-zlib=/mnt/exports/shared/bin/spack/opt/spack/linux-centos7-broadwell/gcc-8.3.1/zlib-1.2.11-7zv5elkj6r5xcrw4mifho5mfhi6wuwpq' '--without-psm' '--without-libfabric' '--without-ucx' '--without-mxm' '--without-verbs' '--without-psm2' '--without-alps' '--without-lsf' '--without-sge' '--with-slurm' '--without-tm' '--without-loadleveler' '--disable-memchecker' '--with-hwloc=/mnt/exports/shared/bin/spack/opt/spack/linux-centos7-broadwell/gcc-8.3.1/hwloc-1.11.11-7tt3mdset5tqvje4uaonjdqm2b3koihp' '--disable-java' '--disable-mpi-java' '--without-cuda' '--enable-cxx-exceptions'

1 error found in build log:
     1125    configure: WARNING:     /usr/slurm
     1126    configure: WARNING: Specified path: /usr
     1127    configure: WARNING: OR neither libpmi nor libpmi2 were found under

     1130    configure: WARNING: Specified path:

It is a very similar problem to: aws/aws-parallelcluster#1008
PMI has been split due to this bug: https://bugs.schedmd.com/show_bug.cgi?id=4511

May I ask to add the package slurm-libpmi?

Thanks
