After looking at this further, I think that this is not a bug.  The
--with-zoltan and --with-parmetis flags are available solely for the purpose
of specifying alternate locations in which to look for those libraries.  If
they are in the default search path then it should be sufficient to specify
*only* '--enable-mbzoltan'.
