[R] Mirror/Package problems in R 2.8.0

[M-J Milloy]

Hello all,

I've searched the lists and the web and not found an obvious answer to  
this; my apologies if I'm overlooking something.

I've used 2.6.x for awhile; this morning, after installing 2.8.0 on my  
Mac OS X 10.5.5 machine, neither install.packages nor the "Packages &  
Data/Package Installer" work and all of my previous packages (which  
had been installed "At System Level" using the GUI-driven process)  
were gone. Attempts to "Get List" through the GUI process fail with

Warning: unable to access index for repository http://cran.fhcrc.org/bin/macosx//contrib/2.8

I've have tried multiple mirrors. I believe the problem is that the  
mirror filestructure is different than what R expects. However, even  
if I fool the GUI process (by using the "Other directory URL" option),  
installing a package still fails.

Thanks for any insight you can provide.
