[Martin Maechler]

Dear Peter,
note that I am CC'ing this reply to the "R - Mac" mailing list, on
which there are knowledgable people for helping you with some of the
Mac specific problems
(more inline below).

Ok, I assume that's close enough to Vanderbilt ..

See, that's a clue:  'gcc' is the GNU C compiler and that (and more)
are absolutely musts for installing many R packages from source.

The readers of R-SIG-Mac will be able to give more exact details,
but in order to get a version of gcc (and other tools) working nicely
with your version of R,
you'll need to install (parts of) the "Xcode" development tools that
Apple provides to you (for free, but you need to "get them").

Best regards,
Martin
