The problem that you report is caused by a terminal hardware failure of the
Leopard machine used to build the CRAN Extras OSX binaries, so that rgdal and
rgeos binaries for OSX have not been built for R 2.15. If OSX users of the
CRAN Extras rgdal and rgeos binaries upgrade to 2.15 and install the
apparently correct 2.15 rgdal (or rgeos), it will fail to load because it was
itself built against R 2.14 - the case reported in this posting.
Until a new build machine is in place, please revert to R 2.14, or delay
upgrading to 2.15 if the CRAN extras binary packages are your prefered method
of installation. More information will follow as soon as the situation is
normalised.
R 2.15 users who install rgdal from source linking to the Kyngchaos GDAL
frameworks will be able to use rgdal in 2.15.
We trust that this has nothing to do with the date - the older Leopard OSX
machine failed about two weeks ago!

Dear list members,
I am running R on a macbook pro with mac osx lion and trying to do some
spatial modelling with R. I have run into a problem in loading rgdal. I
understand that the installation of rgdal in mac is different from other
packages and followed the instructions given in CRAN rgdal page updated
in last January. The rgdal downloaded successfully but didn't appear to
get installed successfully and failed to load. I have copied the screen
print segment below. Is it because of the difference in mac osx version
I am using? I would appreciate if someone could interpret it and suggest
what should I do to get rgdal loaded. I am desperate to use the
functions of this package.
