Orion, I am NOT an Open MPI developer myself. So please don't take my response as speaking for the community. I found the following file useful in understanding WHY libevent is currently bundled in Open MPI: https://svn.open-mpi.org/source/xref/ompi-trunk/opal/mca/event/base/README.openmpi -Paul
Thanks, that was helpful. From what I read there, it does not appear that libevent is not being modified in a meaningful way as it would apply to Fedora. In Fedora, all applications would be built against the same libevent, so that should not be an issue. And assuming that the Fedora libevent properly detects kqueue and epoll (if applicable) that should be okay. Also, have this improvements been submitted back to libevent?
Finally, while openmpi may not need to make use of the dns, http, and rpc events, would it be problematic if they were present in the library?
So other than openmpi expecting to work with a specific version of libevent, I'm not seeing compelling reason why bundling is necessary (at least for Fedora packaging). If there is, please let me know.
