Using numeric bindings with umfpack

Hello,
I use the current version of numeric bindings to use ublas with umfpack. I tried the example umfpack_simple from the test folder:
..
umf::symbolic (A, Symbolic);
  umf::numeric (A, Symbolic, Numeric);
  umf::solve (A, X, B, Numeric);
…
But I got the error:
error: no matching function for call to 'symbolic(sparsematrix_t&, boost::numeric::bindings::umfpack::symbolic_type<double>&)'
it seems there is no function symbolic,numeric and solve. There is one in the namespace detail with different arguments.
Can someone help me please with this example.
Thank you in advance
Niklas
