Thank you! That is exactly what I needed to know. So it is clear that some folks need a build with SSE4 disabled. But SSE2 is supported on the machines of you and the original reporter so I'll try first with SSE2 but not SSE4. The remaining issue is: I need to figure a way to build two binary packages from the source. The other alternative is to disable SSE4 for everyone but I have no idea what performance impact that might have. Regards, -Steve
