I tried building JuMP after compiling v0.7 but am getting errors:
ERROR: LoadError: Failed to precompile ReverseDiffSparse to /Users/MYUSER/.julia/lib/v0.7/ReverseDiffSparse.ji.

How do I interpret these / how can I build JuMP for the latest version 0.7?
If you look at the original error message you'll probably see that StaticArrays (one of JuMP's indirect dependencies) does not load on 0.7. Anyway Julia 0.7 is in a pre-alpha state; there are no tagged prereleases of it yet as of today. It has lots of cool features, but I'd only recommend using it at this point if you're comfortable fixing broken packages and deprecation warnings.
