In my experience, typedefs don't seem to work very well with SWIG (see
for example dolfin_la_post.i).

Does it help if we write

#ifdef HAS_PETSC
    inline const PETScVector& vec() const
    { return vector; }
#else
    inline const uBlasVector& vec() const
    { return vector; }
#endif

instead of

    inline const DefaultVector& vec() const
    { return vector; }

?
