System: Darwin max.local 7.6.0 Darwin Kernel Version 7.6.0: Sun Oct 10 12:05:27 
PDT 2004; root:xnu/xnu-517.9.4.obj~1/RELEASE_PPC  Power Macintosh powerpc
Architecture: powerpc
Machine: Power Macintosh
>Description:
% bmake show-vars VARNAMES=PERL5_ARCHLIB
/usr/pkg/lib/perl5/5.8.5/powerpc-darwin-thread-multi

but when built, perl's archlib is actually
/usr/pkg/lib/perl5/5.8.5/darwin-thread-multi-2level

(when built without threads, the name is "darwin-2level")

>How-To-Repeat:
build perl58 on Darwin.
