Apache: mod_balancer vs. mod_proxy_balancer

I''m trying to setup a mongrel cluster.  I''m relying on
information
collected from a number of sources but I''m relying heavily on
http://mongrel.rubyforge.org/docs/apache.html.

I have noted that a number of sources mention the necessity of having
the mod_balancer module installed in Apache.  However, my primary
source makes no mention of this; but instead, mentions only the
requirement of having the mod_proxy_balancer module installed.  I''m
confused.  In an effort to resolve the confusion, I''m hypothesizing
that the references I''ve read to mod_balancer were really just mal
formed references to mod_proxy_balancer.  I know, it''s a stretch, but
I really don''t know how else to resolve the apparent conflict.  Can
someone please resolve the issue for me?  Is there really a
mod_balancer module that needs to be installed; or, is the
mod_proxy_balancer module sufficient?  Thanks for any input.
