<p style="margin:1.2em!important">libevent(-2.0.so.5) is at available at /lib64. pmix depends on libevent as per the
<a href="https://github.com/spack/spack/blob/develop/var/spack/repos/builtin/packages/pmix/package.py">
spack recipe</a>. Checking for libpmix linkage I do see that it is linked to libevent :<o:p></o:p></p>

<p style="margin:1.2em!important">I’m confused as to why libtool is unable to read use the dependency listing of pmix to find libevent. readelf tells me that libpmix doesn’t have rpaths set for it’s dependencies, could this be the cause of the linker being
unable to find libevent ?<o:p></o:p></p>
