def message; <<-EOS.undent
A TeX/LaTeX installation is required to install.
You can obtain the TeX distribution for Mac OS X from:
http://www.tug.org/mactex/
After you install it, put its bin in your PATH and open a new Terminal tab.
You should also do this because MacTex installs with root ownership:
sudo chown -R $USER `brew --prefix`
That will change all the files and directories back to being owned by you.
