Trouble loading rgdal in RStudio

Question

Why is rgdal failing to load in RStudio (0.94.110) but not in R (2.13.2)?

But, in RStudio:

Anyone know why this is happening? Is there some sort of RStudio default that I don't know about?

Note that rgdal was installed using the following command, having already installed the KyngChaos (GDAL Complete framework):

sudo R CMD INSTALL --configure-args='--with-gdal-config=/Library/Frameworks/GDAL.framework/unix/bin/gdal-config --with-proj-include=/Library/Frameworks/PROJ.framework/unix/include --with-proj-lib=/Library/Frameworks/PROJ.framework/unix/lib' rgdal_0.7-1.tar.gz

Credit due to Josh from the RStudio support staff (see the discussion).

From within RStudio:

> setRepositories()

[enter "1 2"]

> install.packages("rgdal")
> library(rgdal)

gives the normal load behavior:
