[R] update.packages() and install.packages() does not work more because of "Error in read.dcf"

[Juergen Rose]

Hi,

on all my systems update.packages() and install.packages() fails now. I
get the following message:

All systems are gentoo systems with R-2.10.1. 
Also reinstalling of R from sources did not solve the problem.
Any hint is appreciated.
