dnetc v2.9110-519-CTR-11040104 for Mac OS X (Darwin 11.4.0).

Mac OS 10.7.4
Dual 2.8 GHz Quad Core Xeon E5462

I noticed a speed difference between the Universal and the x86 download. The Universal download is running OGR faster.

Tested using the cj-asm-sse2 core.

x86 - 44,756,674 nodes/s

Universal - 56,124,883 nodes/s
