The package version has not changed. You need to recompile from sources 
when upgrading the R version - or just reinstalling the appropriate binary.

R-devel's (to be R-2.1.0) update.packages() has a "checkBuilt" argument 
that is documented as follows:
"If 'TRUE', a package built under an earlier minor version of R is 
considered to be 'old'.
