PyQScintillaX includes binary releases of QScintilla dynamic library for OS X as well as Python bindings. It allows you to use PyQScintilla in your Python project. Unfortunately you can not install this if you don't have Python from official Python website installed on you OS X, so you can't only use the binary dynamic library.
It is highly recommended that you install PyQtX+ before installing this, as it depends on Qt libraries and Python location.
Contact PyQScintillaX@abiusx.com if you had any questions.
