Here what happens is that you use libxfce4util, but it's not in any of 
the modules
you import. What you need to do is to find where this package comes 
from:

> guix package --show=libxfce4util

will tell you (among other things):

> location: gnu/packages/xfce.scm:81:2

so you need to use the module (guix packages xfce). Repeat this for any 
other missing
package variable. The module is the path reported by guix package, where 
you replace /
with spaces and ignore anything after the .scm extension.
