As far as I can tell there was something genuinely broken in your
implementation. I encountered mutex panics in the Perl interpreter
(taken from "pkgsrc/lang/perl5") under a freshly built NetBSD-current
for amd64 yesterday. An easy way to reproduce them was to try to
build "pkgsrc/lang/perl5".

After rebuilding and installing "libc" and "libpthread" from today's
NetBSD-current sources Perl works fine again.

	Kind regards
