As the posting guide says, there is no such version of R ....

Also, I think you did uninstall a previous version, for it is missing 
and the default behaviour of the Apple installer is to delete previous 
versions.

Read the documentation: that is not the way to update!  But given that 
you have done so, run

update.packages(checkBuilt = TRUE)

at the R prompt to download and install updated versions of your 
packages.

We do ask that Mac questions are asked on r-sig-mac, at least if this 
is for the CRAN distribution of R (there are others, and it is 
substantially different from building R from the sources for 
yourself).  One of the many things that is non-standard about that 
distribution is that it hardcodes library paths in its DSOs, so any 
package with compiled code is tied to a small range (e.g. 2.12.[012]) 
of R versions.

You will find a lot of discussion about updating in the recent 
r-sig-mac archives.  See also the rw-FAQ at
