a) You are on unstable... So sorry for the breakage but that is why
'production' should run testing or stable.

b) There is a simple update.package() invocation you can do, it will update
all you packages (in /usr/lib/R as well as /usr/local/lib/R); it needs an
argument you need to set...

c) If you must downgrade, I would downgrade to 2.15.3-2 from CRAN rather than
2.15.1.
