build scipy error cythonize failed

Question

I'm trying to build scipy and I get a RuntimeError:

$sudo python setup.py build Processing scipy/cluster/_vq_rewrite.pyx Traceback (most recent call last):   File "tools/cythonize.py", line 172, in <module>     main()   File "tools/cythonize.py", line 168, in main     find_process_files(root_dir)   File "tools/cythonize.py", line 160, in find_process_files     process(cur_dir, fromfile, tofile, function, hash_db)   File "tools/cythonize.py", line 137, in process     processor_function(fromfile, tofile)   File "tools/cythonize.py", line 66, in process_pyx     raise OSError('Cython needs to be installed') OSError: Cython needs to be installed  Traceback (most recent call last):   File "setup.py", line 209, in <module>     setup_package()   File "setup.py", line 202, in setup_package     generate_cython()   File "setup.py", line 147, in generate_cython     raise RuntimeError("Running cythonize failed!") RuntimeError: Running cythonize failed! 

What are the ways to provide cython to remedy this error?

Python setuptools solved the problem.
