[R-sig-Geo] Installation of rgdal from CRAN on MACOSX does not work

[Agustin Lobo]

While the installation from
http://www.kyngchaos.com/files/software/frameworks/rgdal-0.6.29-1.zip
works fine
the installation of rgdal from CRAN on MACOSX does not work, despite
my previous message that this issue was solved as well
(my confusion was a consequence of mixing both installations in the
same session):
