# Install lupa on Mac if you cannot install it using package manager like macports or homebrew

We use lua 5.1's source codes as a replacement of luajit's source codes.

1. `virtualvenv venv` and switch to the virtual enviornment
2. `pip install cython`
3. `git clone https://github.com/scoder/lupa.git`
4. `cd lupa/`, copy lua 5.1 source tarball here and `tar zxf` it.
5. go to `lua-5.1.5/src` then `make macosx`
6. Back to lupa's root directory, open `setup.py`, change the following lines:


``` python
  # from 

  if not filename.lower().startswith('luajit'):
      continue

  # =>

  if not filename.lower().startswith('lua'):
      continue

  # from 

  libfile = os_path.join(filepath, 'libluajit.a')

  # to

  libfile = os_path.join(filepath, 'liblua.a')
```

Finally `python setup.py install`
