Validate failure

[Simon Marlow]

The following validate failure has happened to me twice, and appears to 
be a parallel make problem (a missing dependency somewhere).  I'm using 
-j3 on a dual-core. I'm posting it here in case anyone else has a clue 
what's going on, otherwise I'll queue it for investigation.

Cheers,
	Simon

why is GHC trying to load the .so for dph-prim-seq?  Is that because the 
.o doesn't exist yet perhaps?
