rsync issues FreeBSD 9.1-RELEASE-p12

[Martin G. McCormick]

	We backup several FreeBSD 9.1-RELEASE-p12 (GENERIC) #0: Tue Apr 29 22:02:25 UTC 2014
systems to a Debian system and have recently started receiving
the following notice:


"This rsync lacks old-style --compress due to its external zlib.  Try -zz."

I tried. it died.
	The messages are relatively new. Whatever changed did so
within the last week or so.

	Our call to rsync starts out
rsync -qvHaz --delete

	I had modified the command as follows:
rsync -zz -qvHaz --delete

this throws a syntax error and 
rsync -qvHazz --delete
does nothing new probably because the first z flag satisfies the
call for compression and the second one just wastes space.

	What is the best way to get compression working again?

Thank you.
