Well, we cannot know if a package needs to be recompiled for another R
version - you cannot assume binary compatibility: a package compiled
under R-x1.y1.z may not work under R-x2.y2.z, for x1.y1 != x2.y2

Well we are building binaries for R-2.9.x and R-devel (to be R-2.10.0)
and stopped building for R-2.8.x. S

No, since we cannot be sure that the new binary works with old R. Source
package compatibility does not imply binary compatibility.

Well, you could try by downloading the most recent version form CRAN and
install via zip file from the Windows GUI. Or much better, install from
sources which is not that difficult.
