An 'Imports:' and NAMESPACE entry appears to be all it takes.  RcppGSL also
has its own LdFlags, but with the diff below against what is in svn head I am
passing R CMD check without a hitch on R release and R devel.  

So for dplyrRcpp, if you just want to suppress the warning, simply alter your
DESCRIPTION and NAMESPACE accordingly.
