I don't think so.
I ***NEVER*** install a package into the standard library.
We have all CRAN packages in a different library, 
(and Bioconductor too) and I typically use about 6 library (paths),
and I don't have your problem.

I only get your warning if I get a version of a package that was
installed previous to 2.3.0 (or it's alpha / beta / rc ) versions.

If it was general, yes, but I think it's not.


Hello Martin and all others involved in this thread,

thank you very much for your time and patience. After having updated the
packages in the standard library, too, the warning message does indeed
not show up any longer by issuing the command library(urca) and similar
with other packages. Just out of curiosity, I wonder what has changed in
these packages (i.e. nlme, foreign, cluster and VR got updated) from
downloading the '.exe' or the tarball in the official 2.3.0 release up
to now?

Best,
Bernhard
