Hi Guy!

There is an open ticket about compiling Cactus with clang:

https://trac.einsteintoolkit.org/ticket/1933

so I assume this road will not work.

I suggest using what is specified in the optionlist, which for homebrew
and the latest ET release is gcc-6. If you experience linking problems,
it's probably a completely different issue: in that case, post again to
the list with the exact error message and we can try and solve that too.

Best,
Eloisa
