Description:

Perl is built without weak references support.
I am using perl 5.8.8-6

Steps to reproduce:

[ambs@eremita tmp]$ cat _.pl
#!/usr/bin/perl
use Scalar::Util qw!weaken!;

[ambs@eremita tmp]$ perl _.pl
Weak references are not implemented in the version of perl at _.pl line 3
BEGIN failed--compilation aborted at _.pl line 3.


And this worked on earlier packages
This task depends upon

I have no idea what that means at all, or why it has been assigned to me. Charles, can you help me out here?

I cannot reproduce this. I also have perl 5.8.8-6 on i686. Are you sure you don't have an older version of Scalar::Util lying around in your PATH? Check with strace perl _.pl and compare with my attachment.
   scalar-util.strace.bz2 (3.1 KiB)

I am not sure yet why this happened. I had Scalar::Util working, and with a Perl update if start giving that result. Meanwhile I reinstalled manually Scalar::Util and it started working again.

So, while I can't assure it was upgrade fault, there was nothing more to make it change :(

Cheers
Alberto

I just downloaded and installed Arch yesterday (I guess that would make it 2007.08-2) from CD. It comes with the broken Perl. I know this because I `pacman -S urxvt`, ran urxvt from an xterm, and it output "urxvt: perl hook 0 evaluation error: Undefined subroutine &Scalar::Util::weaken called at /usr/lib/urxvt/urxvt.pm line 1178."

A search on the subject gave me this fairly explanative URL: http://search.cpan.org/src/ADAMK/Task-Weaken-1.02/Makefile.PL

perl in core does not have this problem.

Yeah, I discovered that after I posted the reopen request, but it wouldn't let me post a comment. Sorry for the hassle.
