Hi Herve

 The "best" way to specify configure.args when there are multiple
packages (either directly or via dependencies) is to use names on
the character vector, i.e.

   install.packages("Rgraphviz",
                    rep="http://bioconductor.org/packages/2.1/bioc",

configure.args=c(Rgraphviz="--with-graphviz=/some/non/standard/place"))


This allows one to specify command line arguments for many packages
simultaneously and unambiguously.

install.packages() only uses configure.args when there are no names
if there is only one package being installed.  It could be made
smarter to apply this to the first of the pkgs only, or
to identify the packages as direct and dependent.  But it is not
obvious it is worth the effort as using names on configure.args
provides a complete solution and is more informative.

Thanks for pointing this out.
