The Boeing machine is a C90, right? That's an older machine than our T90. (SDSC installed a C90 in 1993; it was gone by the time I started working there in 1999.) The T90 can have either Cray or IEEE floating-point. Ours is IEEE. I think the C90 can only have Cray floating-point. If the numconvert test implicitly assumes IEEE (a valid assumption on the vast majority of systems these days), I'm not too surprised that it failed. BTW, our T90 is being decommissioned at the end of this month.
