> Sorry for "Blocker", but it's a license issue. The Spark assembly includes the following,
from JBLAS:

> Unfortunately the libgfortran and libgcc libraries included for Windows are not licensed
in a way that's compatible with Spark and the AL2 -- LGPL at least.
> It's easy to exclude them. I'm not clear what it does to running on Windows; I assume
it can still work but the libs would have to be made available locally and put on the shared
library path manually. I don't think there's a package manager as in Linux that would make
it easily available. I'm not able to test on Windows.
> If it doesn't work, the follow-up question is whether that means JBLAS has to be removed
on the double, or treated as a known issue for 1.3.0.
