Fixing R error in Mac OS X: tar: Failed to set default locale

When I install packages in R in Mac OS X (10.9), I get this warning:

tar: Failed to set default locale

In my shell I have LANG set to en_US and LC_ALL set to en_US.UTF-8.

This command seems to fix it:

defaults write org.R-project.R force.LANG en_US.UTF-8

After restarting R, no more warnings about the default locale.
