Was it actually compiling with an error? Maybe you were just using a
stale version somehow. It has to work in order to import c functions,
which the lsmlib code uses. Functions like malloc, free as well as
functions from liblsmlib.so.

That is the same version that I'm using.

Can you make a little cython program that uses cimport? Try this
arr.pyx:
from libc.stdlib cimport malloc, free
def my_arr():
cdef double *my_array = <double *> malloc(10 * sizeof(double))
my_array[0] = 1.
print my_array[0]
free(my_array)
and run it with this
arrpy.py:
import pyximport
pyximport.install()
from arr import my_arr
my_arr()
run "python arrpy.py", it should just print "1.0". Does that work?
