The boost-sandbox is updated. I hope all is ok. I think there is a 
problem with the implementation of the bindings. The implementation of 
leading_dimension() should not rely on size_m, but rather on size1() and 
size2() depending on the orientation of the matrix. It would solve the 
incompatibility problems with older versions of ublas that have been 
reaised a couple of times.
