Ok, I'll adjust this. I didn't include these dependencies in the first version I created, but used "depends_on: python => 'macfsevents' " instead. I'll put this line back in and remove the Python dependencies. The only issue with the first version was that Ninja-IDE wasn't installed after running 'brew install ninja-ide'. Instead a message was shown advising me to install macfsevents by entering 'pip install macfsevents'. That's why I added the 'if python...' commands to the file.
