Trouble with install.packages() after upgrade to 2.14.2

Earlier today I updated R to 2.14.2 so that I could install the new
ggplot2. Now I'm getting the following error anytime I try and use
install.packages():

Warning in install.packages :

package ?foo? is not available (for R version 2.14.2)

I get this error regardless of the CRAN mirror I use (I've tried a bunch)

and regardless of the interface (Rstudio, the Mac gui for R.app, or the
command line.) I've tried to rectify my mistake by removing R and
installing an older version. I used the command:

rm -rf /Library/Frameworks/R.framework /Applications/R.app

Even after that reinstallation I got the same error (using 2.14.1 and
2.14.0).

I can still install packages from binaries I download from the CRAN
website.

Is this a problem anyone else is having on snow leopard? Any suggestions
for where to go next with my troubleshooting?

Many thanks,

Grant
