My guess is that you have not installed DOLFIN. You need to do a make
install. Check the file

    /home/alex/dolfin/local/include/dolfin/FiniteElement.h

It looks like it has the old version of vertexeval(). It should look
like this:

    virtual void vertexeval(uint vertex_nodes[], ...) const = 0;

and not like this

    virtual void vertexeval(dolfin::real*, ...) const = 0;
