Earlier quoted context omitted.
If you're using Homebrew[1], then it's simply a case of: $ brew install --HEAD vim [1] http://brew.sh
cd /usr/local/Cellar/vim/HEAD/share/vim/vim80/compiler; chmod 644 *.vim README.txt -bash: cd: /usr/local/Cellar/vim/HEAD/share/vim/vim80/compiler: No such file or directory chmod: *.vim: No such file or directory chmod: README.txt: No such file or directory Eh..I'll probably wait a little bit longer.
It's happily just compiled and installed for me.
