Listing multiple versions of Biobase is confusing to me. The idea is 
that specific package 'minor' versions of Bioconductor packages (e.g., 
Biobase 1.5.*) work with particular R releases.

Doing a bit of detective work, I visited


and in the 'Previous Versions' box I clicked on the 1.6 (2.1) link. This 
shows that for R-2.1, I would expect  affy 1.6.7, Biobase 1.5.12. 
reposTools 1.5.19; lars and smida are CRAN packages and are managed in a 
different way but available from CRAN's archive. Focusing on the 
Bioconductor packages, Downloaded the Windows binary of R-2.1.1 (or the 
version appropriate for your operating system; there may be significant 
issues with building old R versions on recent OS versions) from CRAN and 

   biocLite(c("affy", "Biobase"))

What happens?

If you are wanting to do 'new' work, rather than trying to exactly 
reproduce existing work, then as Steve suggests the best thing to do is 
use the current version of R and associated Bioconductor packages, as 
described at
