Problem running alacarte as root

[doktorOblivion]

Getting the following error, anyone have any ideas?

$ sudo xfce4-panel 
[sudo] password for egriffin:

My path is set to:

PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

and there is no PERLLIB setting.

Maybe use gksudo instead of sudo (although why you'd run as root...)?
