This is again the old include-policy problem. Previously the headers of 
ublas were not self-contained. This has been fixed but only on a branch 
(and thus not in the 1.32 release). I plan to merge this branch also to 
the HEAD.

For now, you just need to include storage.hpp before you include lu.hpp. 
In that case, on line 24 of lu.hpp will it recognise unbounded_array 
(which is defined in storage.hpp)
