[R] Can't install packages from ESS command line after upgrading to R 3.3.2 on MacOS

[Gonçalo Ferraz]

Hi, 

I just upgraded R to version 3.3.2 on a Mac OS X system. I suspect something may have gone wrong with the installation (despite a ‘successfully installed’ message) because the R.App is nowhere to be found.
Nevertheless, I can open R in ESS. The problem is I can’t install packages from there. Here is an example of the error message:

> install.packages("rjags")
--- Please select a CRAN mirror for use in this session ---

The downloaded binary packages are in

> library(rjags)

  Referenced from: /Library/Frameworks/R.framework/Versions/3.3/Resources/library/rjags/libs/rjags.so
  Reason: image not found
Error: package or namespace load failed for ‘rjags’

Does anyone know what may be going on?

Thank you,
