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.
