I'm not aware of what alternatives if any are available and for which
versions of CentOS they would be available for... this sort of thing
isn't really something I have a great deal of expertise with. If I
had to guess, the problem is that libavahi and libavformat is probably
a dependency of pjproject/pjnath which is employed by res_rtp_asterisk
Asterisk 11, though I'm not certain about that.  You might be able to
use the old res_rtp_asterisk by grabbing it from Asterisk 10's source
and making whatever tweaks are needed... but I wouldn't recommend it.

Is there some reason you can't get the required libraries for CentOS5?
Without knowing what the differences are between libs you have on the
CentOS5 and CentOS6 machines... I really don't have a lot to go on.
