Sorry if this is the wrong location for basemap toolkit bug reports. Please redirect me if that is the case.
Anyhow, I notice that in pyproj.pyx, the python function
PyAPI_FUNC(int) PyObject_AsWriteBuffer(PyObject *obj,
is incorrectly referenced as
int PyObject_AsWriteBuffer(object, void **rbuf, int *len)
and chokes on 64-bit compiles. My workaround was to more-or-less switch from "int" to "long", but I'm sure there is a better solution.
