The R version is not on the package's CRAN page, e.g.
http://cran.r-project.org/web/packages/sqldf/index.html  I was
thinking of something like this for the Package source line:

Package built source:	 sqldf_0.4-3.tar.gz (built with R version 2.14.0
Patched (2011-10-10 r12345)

This seems important since that line truly is not the source but is
the built source.  The actual source is not uploaded to CRAN or shown.
A transformation has been applied to it so rightfully that should be
tracked back via the R version.

This would make it very clear not only which version of the R package
you are dealing with but which version of R built it and that can in
certain circumstances be important for precisely identifying it.  This
could also be done for the .zip file, etc. shown on that page.

If that level of detail is not feasible then this would be next best
(just showing the R x.y.z version):
Package built source:   sqldf_0.4-3.tar.gz (built with R version 2.14.0)
