Is your CPU capable of SSE2? Unfortunately, the official numpy binary
has been built with an ATLAS library that was compiled for a CPU
capable of SSE2. This means that the SSE2 instructions will cause
older CPUs to crash. The rlm() constructor does call some linear
algebra functions, so I suspect this is the problem.
There is a binary that was built without SSE2. When I dredge it up, I
will let you know.
