Samuel,
Maybe I am doing something wrong but I am getting the same error
on my PowerCenter. I was running mol fine until I upgraded to mol
0.9.41-1. Previously I had been running 0.9.39-1 I think. Haven't looked
at it too closely, just figured I was doing something stupid. Was going
to go looking through the mail list archives and see if anyone had had
this problem before.
I'm running kernel 2.2.14pre9 which I compiled myself. The mol
patches are run time currently.
Rule 0: *** FAILED ***
So what did I screw up?
thanks,
john
