Hi Everybody
I use R2.9.2 on Mac OS X 10.5.2. I tried to install RPostgreSQL from

on CRAN via the package installer. Apparently the program cannot find

I an sure I have gcc-4.0 installed because I can type "gcc-4.0 --
version" in
the terminal and get
i686-apple-darwin9-gcc-4.0.1 (GCC) 4.0.1 (Apple Inc. build 5465)

How do I tell R where gcc is?
It is not R which is asking but RPostgreSQL, so you should take
this up with the package maintainer (but see the posting guide).
(RPostgreSQL does not pick up the compiler from the R, as required in
'Writing R Extensions'.)
But first, was R compiled with gcc-4.0? R 2.9.2 is not current, and
if you update your OS (10.5.8 is the latest), Xcode and R you may find
this works. (I do have
tystie% which gcc
/usr/bin/gcc
under an up-to-date 2.5.8 system, and R 2.10.1 was compiled with
gcc-4.2 according to
tystie% R CMD config CC
gcc-4.2 -arch i386 -std=gnu99
.)
The normal way to tell a configure script the version of the compiler
is to set the environment variable CC.
