[R-sig-Geo] SP 1.0-12 install error

I ran into trouble because I needed to add Rgdal (someone had forgotten
to install it) to an existing 2.15 server and it wanted sp newer than
1.0 but I had 0.9.x. Upgrading this particular machine to 3 was too
risky and would involve verifying all the other running packages could
be upgraded.

For many of my machines I do track the CRAN debs for R updates but not
on deployed servers where an accidental upgrade could break R web
services that are running or long standing analysis code being used by

So yes it would be good if I had gotten the warning in R or saw it in
some news or changelog somewhere. I don't think there's any particular
need to revert as long as people are aware of the issue and the way to
work around it.
