Don't install Jekyll with Homebrew, The security of Homebrew is unknown : https://security.stackexchange.com/questions/105088/osx-homebrew-security-risks
Here is how you install it without homeBrew: with a vanilla OSX el cap: http://digitalshore.io/how-to-install-jekyll-mac-os-x-el-capitan/
The only drawback is that you have to type in your password everytime you use sudo, which isnt a big deal. I rather do that than install more dependencies. You should host your Jekyll config on github anyway, that way you wont have to deal with the command line at all. Here is my article on how to set Jekyll up with github: http://stylekit.org/blog/2016/01/06/The-Jekyll-Setup/
Since then i've made a 30 second video tutorial on how you can setup a jekyll blog on github: https://vimeo.com/154566844
