<p>Thanks for the follow-up Phil, both the problem and the way that
you tracked it down. Another good note for the Slurm Users'

<p class="MsoNormal">It turned out to be a library dependency
for libevent wasn’t being found as needed. While I thought I
was using a shared-location library, I was not. I had
apparently set up /etc/ld.so.conf.d on the build host to use
/usr/local/lib which… has libevent in it. But none of the
other nodes had this. The problem became apparent after going
to each node and running pmix_info.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This means I should remove the ld.so.conf.d
entry and rebuild everything against the preferred set of
libraries. Otherwise pmix appears to work as expected now.<o:p></o:p></p>

is available -- not just the versioned .so, e.g. .so.2.
Slurm requires that .so symlink. Some distros split
packages into base/devel, so you may need to install a
pmix-devel package, if available, in order to add the
.so symlink (which is considered a "development" file).<o:p></o:p></span></p>
