Compiling packages with specific gcc

Hi all,
I'm wondering if/where I can go to tell R to use a specific version of
my gcc compiler when installing packages from source, via
`install.packages("...", type='source')` or when running `R CMD
INSTALL some_source_packge.tar.gz` from the command line.
The reason I ask is because I've downloaded gcc-4.4 from HPC/OSX[1],
and it unfortunately puts the compilers in /usr/local/bin/gcc, w/o
version info (it would be nice if it were /usr/local/bin/gcc-4.4). R
tries to use this when compiling, but these compilers do not support
the "-arch=..." flags, so it bombs.
I've been hunting around in the tools:::.install_packges code and also
the "R Installation and Adminstration"[2] document, but can't find
what I'm looking for. I have a feeling that perhaps I can put
something into my ~/.R/Makevars, or ~/.R/Makevars-i386-apple-
darwin8.11.1 file, but I'm just taking stabs at the dark, so not
having much luck.
I can work around this by temporarily removing /usr/local/bin from my
path when trying to `R CMD INSTALL` packages by source, but I was
hoping there might be a more elegant solution. The fact that
installing by source gets the `make` command from the system
environment makes me a bit hopeful, but I'm not really sure.
Thanks for any help,
You can pass configure args with the configure.args parameter to install.packages. I'm not sure how many you need to set, but you'll likely need to set CC, CPP, CXX, F77, FC, OBJC, and maybe some of the associated flags. You can see the list using "R CMD config" in the console. Duncan Murdoch
