Yes, you have the wrong binaries!! You have binaries for R 2.7 but you  
need binaries for R 2.8.
I can only repeat that over and over again. Get binaries for R 2.8.0!  
They are in

http://cran.r-project.org/bin/macosx/universal/contrib/2.8/

(replace the host with your mirror if you wish, but make sure there is  
2.8 in the URL!)
The most reliable way is to use install.packages to fetch them, but if  
you have to fetch them manually, make sure you get the right ones!

Do NOT do that! R 2.7 and R 2.8 are NOT binary compatible. Most  
symbols will be fine, but some won't. You simply have the wrong  
binaries - again 2.7 binaries are NOT meant to be used with R 2.8.0.

Cheers,
Simon
