in reply to Recent perl distributions without support for Scalar::Util::weaken() ?

I had a similar issue with List::Util on Ubuntu Warty. Apparently, it doesn't come with the XS version of the module. The issue might be similar with Scalar::Util. Even worse, the pure-perl version of Scalar::Util (look in /usr/share/perl/5.8/Scalar/Util.pm, search for 'ESQ') doesn't implement all the features of the XS version.
