 It helps to copy-and-paste the errors that you are seeing.

 In any case, Cython 0.18 works okay on master's mtrand.pyx sources.


 Well, this is the first error:

 cython mtrand.pyx

 Error compiling Cython file:

 mtrand.pyx:177:41: Python objects cannot be cast to pointers of primitive 
 types

It looks like Cython 0.18 removed the members of flatiter in its copy
of numpy.pxd in favor of the macros that are recommended for numpy
1.7. The irony is not lost on me.

This should be (double *PyArray_ITER_DATA(itera)[0]).

I'm not sure why it appears to work in master, since this code in
mtrand.pyx did not change.
