I tried to install the R packages for the Debian GNU/Linux Woody distribution.
I added "deb http://cran.r-project.org/bin/linux/debian woody main" to
my /etc/apt/sources.list, and ran dselect with the apt-get method.
I selected all of the R packages that I could find. The installation
appeared to fail, because r-base and r-recommended both depend on blas2.
I cannot find a Debian package for blas2 in the Debian archives, nor in
the CRAN archives. blas1 is in the Debian archives for both Potato and Woody.
I also checked the package list for your Debian Potato distribution, and
I found no dependence on blas2 nor on blas1 there.

Blas2 is a so-called "virtual package" which is provided by the actual blas1
package, as well as by any of the four atlas2 packages (atlas2-base,
atlas2-p3, atlas2-p4, atlas2-athlon). I highly recommended the atlas2
packages (esp if one matches your processor) as the speed gain can be
tremendous for linear algebra operations

Also, I'd recommend using apt-get instead of dselect; a simple

    $ apt-get update; apt-get install r-base

should have resolved that dependency for you.

Note that you can pick a closer mirror; I use cran.us.r-project.org.

Hope that helps,  Dirk
