Hmmm. Recent versions of R require correctly installed versions (using R
CMD INSTALL) of the packages. It is hard work to get a file called *.ZIP
(rather than *.zip) that contains a valid binary package for Windows.
I'd vote against such a change, since the recent behaviour suggests
perfectly well that the file probably won't work.
