Recall that we link with (post Rcpp 0.11.0) 

       PKG_LIBS= $(LAPACK_LIBS) $(BLAS_LIBS) $(FLIBS)

and note the absence of ARPACK :)    So right now, the header-only build of
RcppArmadillo means no eigs!  

If you export it, though, we may be able to use it.  

We should talk off-list and work this out,
