@fommil I have the native vecLib BLAS/LAPACK shipped with Mac OS X and
OpenBLAS installed for testing. OpenBLAS is not on the search path. I deleted
both and re-ran the benchmarks and got the same result for netlib-java, so I
believe it used the native library from netlib-all. This is the message I got
when running the benchmarks:

@MLnick I talked to @etrain about the issues they've seen with breeze at
the very early stage of mllib, but it seems hard to recall exactly what the
issues are and how to reproduce them. @dlwh should be able to answer what has
changed in breeze since then. Actually, I'm quite surprised to see that breeze
maintains good performance with heavy implicit usage.
@MLnick @fommil I'll add MTJ in the benchmarks when I have some free
cycles. But please understand that this PR is for Spark/MLlib, where we cannot
proceed without clearing the license problems. I don't quite understand the
detailed reasoning, but I do know many companies would avoid LGPL.
@fommil It would be great if you can add Apache license to jniloader dual.
That would clear the license issue of breeze. I understand changing MTJ's
license needs some communication with its original author and hence time, but
it would be great if you have a good estimate on whether it is possible and how
long it may take.
