[Rd] Help with libiconv problem

[Mick Jordan]

A couple of my colleagues are having problems building R-3.2.4 on Mac OS 
X El Capitan somehow related to libiconv. I personally don't have any 
problems on either of my Macs. I'm hoping thie make log might trigger 
something in the readers of this list:

We always get the unknown timezone messages which I think are unrelated 
but I'm curious about those.
