[R-sig-Geo] Build rgdal for Yosemite?

[Gilles Benjamin Leduc]

Hi, 

I try to use rgdal on R with OSX Yosemite. I tried then to reinstall it (I upgraded R recently) 

>> library(rgdal)
> Erreur dans library(rgdal) : aucun package nommé ‘rgdal’ n'est trouvé
>> install.packages("rgdal")

How to build it? or can anyone make it available?
