osx-homebrew.cfg does not work out of the box on Yosemite
Issue #1784
closed
When installing ET anew on Yosemite with the instructions in osx-homebrew.cfg, the build fails because homebrew gets the latest version of gcc (5.1), which is currently not the one then specified in the cactus compilation options (4.9).
This problem was encountered by a student who approached ET for the first time.

Does it work to replace "gcc" with "gcc49" in the "brew install" line? I'm not an expect on homebrew, but it seems like you can select versions in this way.
I experimented with using gcc 5.1 with MacPorts, but didn't like the result, as many dependent libraries didn't come with gcc 5.1 variants, and MacPorts insisted on compiling a lot. 4.9 seems to work quite well for now.
