It is if you use the proper version of R.

But it isn't a bug.  As per your previous message, you were using R-1.9.1 
and using 'devel=T'.  If you followed the instructions properly, you would
be using R-devel (which is currently R-2.0.0. Alpha), in which you'll find
that the 'getRVersion' function is now part of R and not in reposTools,
thus the removal of said function from reposTools.  Furthermore, if you
followed the instructions properly and used the release version of BioC
packages with your R-1.9.1, you wouldn't have found this "bug".
