thanks for your input Herv?. Glad to hear I'm not the only one still having
this issue.

In my opinion install.packages should stop with an error (instead of a
warning) if this happens.

However even if you want to keep the warning, at least make it so that
users can set options(warn=2) to get an error if they want one. I tried
setting options(warn=2) but for some reason I still get a warning.

I believe that is a bug in install.packages -- if I specify options(warn=2)
it should convert that warning to an error (but it currently does not).
