`make test' of perl5.0004 package reports that test lib/filecopy FAILED.

	cd /usr/pkgsrc/lang/perl5; make ; make test

Rerunning `( cd ./t ; ./perl lib/filecopy.t)') shows that test 8 is
causing perl to coredump.  Looking at the corefile suggests the
problem is calling rename(2).


I beleive the package maintainers were aware of this, but there
appears to be a bug with redundantly-defined symbols in shared
libraries on NetBSD/pmax.  (e.g., rename(2) is defined in both libc
and in lposix).  The symptom is that a process wil coredumps when it
calls the redundantly-defined symbol.

(I'm told OpenBSD/arc loses similarly).

Here, rename(2) is defined in both -lposix and libc is what triggers
the Perl coredump.  Editing out the `-lposix' from the configured
Makefile _by hand_ and relinking and rerunning perl fixes the
coredump.  The result passes Perl's `make test'.

It'd be very, very nice if the NetBSD package could fix that in the
Perl-geenrated Makefile on NetBSD/pmax systems, at least until the
apparent dynamic-linker bug is resolved.

I'd sooner that Perl on pmaxes used the BSD semantics rather than
coredumping, but I don't know of a good way around this that doesn't
affect all NetBSD ports.
