[rt-users] Scalar::Util::weaken error

[kjcsb]

I have recently run a yum update and am now getting the following error


[Tue Jan  3 01:14:31 2012] [error]: Scrip Prepare 15 died. - Undefined subroutine &Scalar::Util::weaken called at /opt/rt3/lib/RT/Action/Generic.pm line 107.

Stack:

Note that Scalar::Util is installed
perl -MCPAN -e 'force install "Scalar::Util"'

Running make install

perl -v

This is perl, v5.8.8 built for x86_64-linux-thread-multi

After researching this issue there is some discussion of an issue with certain packaged versions of perl. Refer https://bugzilla.redhat.com/show_bug.cgi?id=507378. However when I run the command that should error it doesn't:


perl -MScalar::Util=dualvar -e 1
Any advice appreciated.
