cimport cython.view array as cvarray - compilation error

edit

I get a compilation error if I try something even as simple as:

from cython.view cimport array as cvarray
cdef arraytest():
    pass

I get the same error using the notebook and on loading from the sage command line. I have installed a fresh copy of cython.spkg to no avail.

I must be missing something obvious, but what?

Sage version 5.11; gcc version 4.7.3; running on ubuntu 13.04

This is the error:
