I did so and restarted. I checked my ~/.Rprofile setting and that is  
not the source of the persistent non-R.Framework libpath. I reviewed  
the Macs section of the Installation Manual and it tells me that it's  
basically a Unix device and that I should review the general R  
instructions.

Reading the Installation and Administration Guide in section 6 I see  
several areas about which I am uninformed:

 > R.home(component="home")
[1] "/Library/Frameworks/R.framework/Resources"

I don't have an R_HOME/etc/Rprofile.site

I think I have found my problem because:
Sys.getenv("R_LIBS_USER")
                R_LIBS_USER
"~/Library/R/2.10/library"

So I tried Sys.setenv(R_LIB_USER = "")

I thought from the help page that this would report a logical value  
for success or failure, but got neither. Wish me luck.
