Thanks Dirk and Charles for the pointers.  I'm now running a locally
installed R 2.15.3 and packages until the dust settles with 3.0.0.

I just noticed that many sid packages have now been rebuilt against R
3.0.0.  Kudos to Dirk and the team!  However, I don't understand how
this works for packages that have an upstream Depends on R < 3.0.0.  One
of these is nlme, and yet r-cran-nlme has been rebuilt against R 3.0.0,
even though it fails to load in this latest R with:

R> library(nlme)
Error: package ‘nlme’ was built before R 3.0.0: please re-install it

What am I missing?

Thanks,
