Chkrootkit error in output

Hi i have set Chrootkit to scan every night with cron but in my mail i get this error

Anyone have idea how to fix ?
Im running Debian Etch with su_php

 

This is my cron command

0 3 * * * (cd /usr/local/chkrootkit-<version>; ./chkrootkit 2>&1 | mail -s "chkrootkit output my server" [email protected])

ill try and run it from command line when i get home

 

When running from command line i get this

 

This is what I've found:
http://sidux.com/PNphpBB2-viewtopic-t-11837.html
http://groups.google.com/group/linux.debian.user/browse_thread/thread/a84de8e58522fc83

Did you check if there's an upgrade for chkrootkit available?

 

Thats all i could find also i guess í have to wait untill a update to get it fixed.

Tnx annyways
