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
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.
