[Rd] package installation order

[Kuhn, Max]

I have roughly 80 or so packages sources. These were obtained by taking
a snapshot of certain CRAN packages a few months ago using 

   install.packages(
      pkgs = pckNames,
      destdir = "/home/max",
      repos = "http://cran.r-project.org"
      dependencies = c("Depends", "Imports", "Suggests"))

We need to install these versions of the packages across a few different
architectures/systems (linux, solaris, 32- and 64-bit). Right now, we
are constrained to version 2.5.1 (I know, I know). 

Right now, I'd use 

   tarList <- list.files()
   tarList <- grep(".tar.gz", tarList, fixed = TRUE, value = TRUE)
   install.packages (tarList, repos = NULL)
	
to install, but the package dependencies are ignored. For example, XML
gets installed after other packages that depend on it.

I've looked through ?install.packages and I have tried using 

   install.packages (
      tarList, repos = NULL, 
      dependencies = c("Depends", "Imports", "Suggests"))

but this did not appear to change the install ordering. 

Is there a simpler way to do this rather than trial and error?

Thanks,

Max
