I see. Yes, looks like libevent 2 is required. This one should be easy
to fix (unlike libGLES requirement).

This might seem silly, but what I'd suggest (I'm sure there are other
solutions, but this one works) is to install official postgresql yum
repo for SL6. (http://yum.postgresql.org/). Do *NOT* install repo from
9.4. Version 9.3 (any of 9.0-9.3, but no reason to pick earlier) is what
you need.

You don't need to actually install postgresql - it's just that when you
DO install it, it always replaces libevent 1.4 with libevent 2 and
provides libevent 1.4 binary for old packages in new package
compat-libevent-1.4. The reason you shouldn't pick 9.4 repo is that it
doesn't seem to provide compat-libevent anymore (maybe it will be built
in the future, 9.4 was just released, but for now it's not there).

Anyhow what you have to do is: remove libevent-devel, install repo for
SL6 from http://yum.postgresql.org/repopackages.php#pg93 , install
libevent-devel. I think yum will pull compat-libevent14 automatically,
if not, try installing them both. One way or another, libevent 2 and
devel package will be available on your system, from now on, and compat
library will be installed for applications that were linked to older
libevent.

This replacement of packages is totally safe (everyone who uses
postgresql 9 in EL6 does it, anyway), just remember to keep postgresql
repo enabled from now on.
