That's not true for me.  Currently 3808 binary packages are available 
out of 3912 source packages, and all the *binary* packages should be 
found (but XLConnect is not one of those).  If you are seeing something 
different, do

(a) try the CRAN master
(b) report if R.app is not seeing all the packages there.

The errors can be seen at 
http://cran.r-project.org/web/checks/check_results_XLConnect.html: it 
seems the CRAN Mac build machine does have problems with several 
packages using rJava.  Since the latter is Simon's package, he is 
probably well aware of it.

It is worth pointing out that Java on OS X is something of a security 
nightmare, and maybe especially on Leopard (which the build machine 
perforce runs).  A couple of my students have found (the hard way) that 
Macs are not immune to malware.
