No. As the FAQ asked re bug reports, please don't post speculation rather than problem description.

Do you mean 'make a binary version of the package ....'? Binary packages are (on all platforms, but specifically on Windows and Mac OS X) intended for use only on the same 2.x.[012] versions of R. That warning was not meant to be ignored!

If you had bothered to read the CHANGES file you would known that the location of files on Windows binary installations changed in R 2.12.0: of course there is no way that R 2.10.0 (as the posting guide points out there is no '2.10') could know that was going to be changed a year later.

The solution is for you to prepare a binary package for each version of R you want it available with and make it available on your own repository.
