Trouble installing rgdal --- libcurl.4.dylib

Hello everyone,

I have trouble installing the rgdal package.
I run R 2.15.0 on Mac OS 10.6.8.

I followed the instructions given by Roger Bivand, who develops rgdal and ran:
library(sp);
setRepositories(ind=1:2)
install.packages("rgdal")
--- SVP s?lectionner un miroir CRAN pour cette session ---
essai de l'URL 'http://www.stats.ox.ac.uk/pub/RWin/bin/macosx/leopard/contrib/2.15/rgdal_0.7-8.tgz'
Content type 'application/x-gzip' length 13810017 bytes (13.2 Mb)
URL ouverte
==================================================
downloaded 13.2 Mb

It seemed to be OK, but when I try to call rgdal, I get:
library(rgdal)
Error in dyn.load(file, DLLpath = DLLpath, ...) :
 impossible de charger l'objet partag? '/Library/Frameworks/R.framework/Versions/2.15/Resources/library/rgdal/libs/i386/rgdal.so':
 dlopen(/Library/Frameworks/R.framework/Versions/2.15/Resources/library/rgdal/libs/i386/rgdal.so, 6): Library not loaded: /usr/lib/libcurl.4.dylib
 Referenced from: /Library/Frameworks/R.framework/Versions/2.15/Resources/library/rgdal/libs/i386/rgdal.so
 Reason: Incompatible library version: rgdal.so requires version 7.0.0 or later, but libcurl.4.dylib provides version 6.0.0
Erreur : le chargement du package / espace de noms a ?chou? pour ?rgdal?

It seems that the problem comes from libcurl.4.dylib.

Does anyone know what I should do?

Please wait for the CRAN version, it should be up today or tomorrow. Alternatively you can upgrade you system (we will be removing Leopard support soon anyway). My understanding is that the CRANextras binaries are now cross-compiled, so they don't always work on Leopard anymore.

Cheers,
Simon
Thank you very much,
Pierre.
