[mrtg] List::Util object version 1.18 does not match bootstrap parameter 1.19

Hi all,

I believe that after updating my Fedora with yum i get the following errors:

2008-03-24 09:46:01 -- Started mrtg with config '/home/mrtg/cfg/stat.cfg'
2008-03-24 09:46:03 -- List::Util object version 1.18 does not match bootstrap parameter 1.19 at /usr/lib/perl5/5.8.8/i386-linux-thread-multi/XSLoader.pm line 88.
2008-03-24 09:46:03 -- 2008-03-24 09:46:02: ERROR: fork 0 has died ahead of time ...

Don't you know anybody, why it is so please, or what do I need to do?

Thank you so much
