Happened when you upgrade bt3 to Slackware 12.1 ^_^
Workaround :
k-elektronik ~ # whereis fortune
fortune: /usr/games/fortune /usr/man/man6/fortune.6.gz /usr/share/man/man6/fortune.6.gz /usr/X11/man/man6/fortune.6.gz
k-elektronik ~ # ln -s /usr/games/fortune /usr/local/bin/fortune
Travelling Linux 
thanks
Thanks, still useful for custom .bashrc in slackware 13.1!
Thx, worked in Debian 5.0 -> 6.0 case.
Thank you so much. I had trouble adding the fortune and cowsay commands to my PATH. This simple solution bypasses all that.
