Sylvain Corlay added the comment: Ned, that is because these packages (lxml, cffi) have header files as `package_data`, instead of `headers`. This is why they are being copied into site-packages. People willing to include them must either rely on knowledge of their location, or a python functions returning if (like numpy's get_include)
Distutils provides a standard way of distributing headers. These are passed to the setup function via the `headers` keyword argument, which triggers the `install_headers` command. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26955> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
