[R] New R - recompiling all packages

[Arne.Muller@aventis.com]

Hi All,

I'm running R 1.7.1, and I've installed some additional packages such a
Bioconductor. Do I've to re-install all the additional packages when ugrading
to R 1.8.0 (i.e. are there compile in dependencies)?

	thanks for your help,

	Arne
