Update:I was able to resolve this by reinstalling Scalar::Util
Thanks to Joost, et al from the chatterbox!

So i got to work this morning and found an unpleasant surprise on one of my development projects. I tracked it down to this:

perl -c XML_query_maker_support.pl
Weak references are not implemented in the version of perl at /usr/lib
+/perl5/site_perl/5.8.0/Tree/Simple.pm line 9
BEGIN failed--compilation aborted at /usr/lib/perl5/site_perl/5.8.0/Tr
+ee/Simple.pm line 9.

This module worked when i left work yesterday, but...

Our network admin has been upgrading Redhat on this machine, and i have no idea why this occured. We're still using the same version of Perl:

 perl -v

This is perl, v5.8.0 built for i386-linux-thread-multi
(with 1 registered patch, see perl -V for more detail)

And when I perl -V

From that output, i see that the registered patch was installed february 1, 2005, so it isnt anything new. I'm completely at a loss as to how to deal with this.

I could try re-installing Tree::Simple, and the 6 other Tree::Simple visitors that i need, but i don't know if that will help things at all.

Incidentally, line 9 of Tree::Simple is this:

use Scalar::Util qw(blessed weaken);

Anyone have any idea what might be going on?

I use the most powerful debugger available: print!
