SFML gcc - MacOS

[Joel via Digitalmars-d-learn]

In getting DSFML (http://dsfml.com/) working. I found gcc takes 
for ever to install, is there some thing wrong? (I posted in 
https://github.com/Jebbs/DSFML, but no replies). Maybe just 
install Xcode CLT (some how), and uninstall gcc. I've had this 
problem for a while now.

I would appreciate any help.
