Yes.

I still cannot reproduce it - it works perfectly for me:

gammu:urbanek$ uname -srp
Darwin 8.1.0 powerpc
gammu:urbanek$ ls -ld /tmp/bar
drwxr-xr-x   2 urbanek  wheel  68 Jun  9 12:38 /tmp/bar
gammu:urbanek$ cat ~/.Renviron
R_LIBS=/tmp/bar
gammu:urbanek$ echo =$R_LIBS=
==
gammu:urbanek$ R

If you want to try to debug your problem, you may want to look at  
$R_HOME/library/base/R/Rprofile, because that is where .libPaths gets  
set.

Can you, please, check the ls -ld $R_LIBS output?

BTW: That works only for LS-started applications.
