Description

When running tests with the new ML package, I get:

[info] spark.SparkException: Job failed: Task 5.0:0 failed more than 4 times; aborting job java.lang.UnsatisfiedLinkError: org.jblas.NativeBlas.dgemm(CCIIID[DII[DIID[DII)V

Shivaram mentioned I should install a Fortran package:

sudo apt-get install libgfortran3

And it worked after that. We should figure out exactly what the dependencies are here list in the build instructions that they exist. Also, if these are runtime dependencies we should mention them clearly in the main Spark docs.
