help please, updating rsync on OS X

[Scott Griswold]

Hi,
I tried using rsyncX which is a GUI front end for rsync and as it  
turns out, the installer downgraded the current version from version  
2.6.3  protocol version 28 to version 2.6.6  protocol version 27.
I would like to learn more about how to get a newer version of rsync  
installed. Where would be a good place for a beginner to start?

Thanks Much,
Scott G.
