Well, that's what I think as well .. so my question is, why is it there 
then?

My guess is that it's due to the fact that the script was written for 
all unix platforms, therefore it explicitly sets it since some unixes 
need it. It is in src/scripts/R.sh.in (this one is from today's 
R-devel):
## NOTE:
## We must set this here rather than in the main binary.
: ${R_LD_LIBRARY_PATH=${R_HOME}/bin:@R_LD_LIBRARY_PATH@}
if test -z "${@shlibpath_var@}"; then
   @shlibpath_var@="${R_LD_LIBRARY_PATH}"
else
   @shlibpath_var@="${R_LD_LIBRARY_PATH}:${@shlibpath_var@}"
fi
export @shlibpath_var@

... and in turn autoconf generates:
darwin* | rhapsody*)
[...]
shlibpath_var=DYLD_LIBRARY_PATH

So what's the most clean way to fix that? One more "if" or for Darwin 
in R.sh.in? Remove X11 from R_LD_LIBRARY_PATH for Darwin?
