No such file or directory: helita/io/anapyio.c

Hello. I was following this installation instructions, but unfortunately couldn't install Helita neither using pip nor via setup.py. I get this error:

...
clang: helita/io/anapyio.c
clang: helita/io/src/libf0.c
clang: helita/io/src/anacompress.c
clang: helita/io/src/anadecompress.c
clang: error: no such file or directory: 'helita/io/anapyio.c'
clang: error: no input files

And indeed, there is no helita/io/anapyio.c in the repository. Am I perhaps missing something?

My environment is on Mac OS:

Oh, silly me, I was missing cython package.

Yes, you need cython to build the .c file from the .pyx.
