Dear R,
  I am attempting to install 2.0.1 on a Debian system and getting an error
that appeared for people installing 2.0.0.

Warning message:
package seems to be using lazy loading already in:
makeLazyLoading("tools")
Error in get(x, envir, mode, inherits) : variable
".install_package_description" was not found
Execution halted


platform i686-pc-linux-gnu
arch     i686
os       linux-gnu
system   i686, linux-gnu
status
major    1
minor    9.0


?????
  Thanks
