error reported cython

fatal error: utility: no such file or directory

you've not done set compile c++ rather c. c compiler unable find c++ standard library (hence "no such file or directory" error).

you need tell pyximport use c++ instead of c setting .pyxbld file. alternatively use setup.py in c++ mode instead of pyximport.
