I'm not sure of the source of the problem with the conda 2016.09 release on
my Windows box, but I was able to revert to a 2016.03 release with a *conda
install -c rmg rdkit=2016.03**

conda couldn't seem to solve the specifications automagically, but after I
uninstalled boost and did the above command, it identified the proper boost
to install along with the 2016.03 rdkit.

I now have a functioning rdkit again, but would still be interested in
hearing from anyone that experiences a similar problem.
