Hello,

My problem was that I didn't have XCode installed until a few minutes ago,
and I can confirm that compiling from the source works (x86_64 on OSX10.6.4,
R2.11.1 - sorry about that).

The error codes I pasted on my earlier e-mail were copied from the CRAN, the
log notes on why a Mac binary of the mapdata package wasn't available (
http://www.r-project.org/nosvn/R.check/r-release-macosx-ix86/mapdata-00check.html
).

As there's no obvious problem with the source code itself, the problem is
most probably with those that maintain the MacOSX binaries on CRAN.

I assume there may be some novice users who might not want to go through the
trouble of trying to compiling source code and much rather install just the
binary versions of packages, and I do hope that the overseers of the MacOSX
binaries would give the compile another try...

Thanks for all the help, and cheers.

Jooil
