That works. Throw a warning if we can't find it and be done with it all. We
probably ought to cache the ultimate location once we find it, perhaps
keeping the FID and keeping the thing open so it can't be swapped out from
under us. Or maybe that's just too much work and we should re-search if the
one we found the first time's not there later.

I like! :) Hoff did say that the perl prefix was in the process of being
registered. Maybe we should assault the new lexical warnings stuff to set
$^E as it goes along.

Yelling if VMSPIPE.COM can't be found in @INC is probably good enough. The
only reason to do anything else would be if .ZIP/.tar.gz packaging of the
perl tree happens, but that's got issues with shareable images as well so
we can cross that bridge once it's actually built...
