sparse_matrix was recently renamed to mapped_matrix. You should try the CVS
version of ublas.

I'd like to guess, what the problem is without running the compiler:
You tried to do a debug build of a matrix containing integers. There is a
type_traits missing that defines 'real_type' for any integer type, but this
trait is needed by some debug checks (Should we add this?).
As a quick&dirty fix you can uncomment the lines 6465:
typedef T real_type;
typedef T precision_type;
in traits.hpp.
Please check if the example compiles using the "DNDEBUG" compiler flag.
