I think this is a mislabelled /var/cache/ldconfig.  Check if yours is
like this

# ll /var/cache/ldconfig -Zd
drwx------  root root system_u:object_r:ldconfig_cache_t /var/cache/ldconfig

If not:

# fixfiles relabel /var/cache/ldconfig

After that

# ldconfig

will find any new libs.

Dunno.

Dunno.

Is dbus running?

service messagebus status

Yep.

ldconfig can be straightened out just be re-running it.  The libs from
the packages were already installed okay.

Up to you...

You might want to force a whole filesystem relabel...

touch /.autorelabel

and reboot.  But if there are no more funnies after fixing ldconfig I
probably wouldn't bother.
