[R-sig-Debian] downgrading to R 2.15.1-4 from sid beta 3.0.0

[Sebastian P. Luque]

Hi,

I'm using sid, and this morning I carelessly upgraded R core packages,
which are currently at the beta 3.0.0 version.  I hadn't read that
packages need to be re-built to be used with this beta version.  I'd
happily do that locally (via 'install.packages') for those that haven't
yet been re-built in Debian, but some just don't allow that, notably
nlme which has a Depends on R (≥ 2.14.0), R (< 3.0.0)...  So I decided
to just downgrade the base packages, temporarily remove the r-cran-*
dependendants, and then install nlme (and others) locally until the
April release of 3.0.0 and the rest of the packages get rebuilt in
Debian.

Is there a more efficient way to deal with this when a new R requires
such rebuilds in Debian?

Thanks,
