Did you try to make at least libunwind taken from the dependencies? 
Julia has many dependencies and wants to build them itself, but for some
of them I managed to make Julia take prebuilt ones. If you tried and 
failed to use prebuilt versions of libunwind (and maybe suitesparse),
I won't try to change it; otherwise it seems worth it to try.
