This is a result of a (small but important) interface change in the 
DOLFIN linear algebra library.

Before (until 0.7.0-1) Vector was a typedef for either a PETScMatrix or 
a uBlasMatrix. As a result, the things you could do with a Vector 
depended on how you had configured DOLFIN.

Now, Vector is a (very lightweight) wrapper for either a PETScMatrix or 
a uBlasMatrix that only supports the functionality of the GenericVector 
interface. So, no matter how you configure DOLFIN (with PETSc or uBlas), 
the code will always compile.

Your problem is that you have used Vector, but have used uBlas-specific 
functions that are not available in the common Vector interface.

So, you need to either just use the functions in Vector or change from 
Vector to uBlasVector if you need to use functionality that is 
uBlas-specific.
