ok here is my test.pyx:
------------------------------------------- cimport _soya
cdef class Test(_soya.CoordSyst): pass
-------------------------------------------
and here is my setup.py. i trimmed off what i think i dont need and also
found a class that let me pass include directories to pyrex

im slightly confused. my c compiling skills are not good :)
