When trying to package the by-now-gargantuan Rmetrics for Debian (which is still ongoing), I looked around for some Depends builders. Turns out that BioC has this. E.g. the following worked for:

## > install.packages("Biobase", repo="http://www.bioconductor.org")
## > repos <- Biobase:::biocReposList()
## > install.packages("pkgDepTools", repos=repos["bioc"])
## > library(pkgDepTools)
## Loading required package: graph
## Loading required package: RBGL
## > CRANdeps <- makeDepGraph(repos["cran"], type="source")
## > getInstallOrder("Rmetrics", CRANdeps, needed.only=FALSE)

worked for me. I meant to add some code for Graphviz visualization (or look for it, Seth et al probably already wrote it) but what you get from getInstallOrder() should suit your needs here.

Hth, Dirk
