The C modules of Python is not a script file and it must not work even if you just copy it. You must rebuild the Python and modules against system’s curses library.
The lack of library or development headers of curses (e.g. libncursesw5-dev) might causes those issues. Please confirm if you have enough package for the module.

という事なので、pythonの再構築が必要らしい
