I think you are mislead:
CRAN accepts source packages only. Binaries are made by CRAN (or more particular by myself in Dortmund). For new packages or updates as of today, we make binaries for R-2.12.x and R-2.13.x available. Note that between major releases of R, you cannot assume that packages will work. The help system changed in R-2.10.x (and no binaries are compatible before vs. after the R-2.10.0 version) and the location of libraries in R-2.12.x changed under Windows.

If you need a binary for R-2.8.x, you will have to INSTALL from sources with R-2.8.x, otherwise we cannot guarantee compatibility. Note that R-2.8.1 is unsupported and 5 major releases back!
