Weird. I sucessfully built it in one go on a 2x 2GHz Xeon with a 7-CURRRENT kernel in a ~6.0-BETA2 chroot. I'm on our cluster, I'm looking in to having per hardware configuration libmap.conf files so users will link against a version optimized for the head node and then pick up the right version on each node. If that works out it might be useful to have packages some day (even ones that deliberatly disable much of autotuning) just to let me install something to link against. -- Brooks --=20 Any statement of the form "X is the one, true Y" is FALSE.
