[BioC] repos tools

[peter]

Dear List,

I realize that problems surrounding getBioC have been discussed before, but 
the discussion do not seem to be relevant to my question.
I am running a Debian Sarge system and R 1.91 installed as a debian package.
When I enter
>source("http://www.bioconductor.org/getBioC.R")
>getBioC()
I get the error message
Loading required package: reposTools
Error in pkgs[, "Package"] : incorrect number of dimensions
Error in getBioC(): needs reposTools to continue

(various arguments to getBioC such as force=T do not help)

I would be grateful for any tips!

Peter
