The problem is the path that the panel uses to search for plugins. I'm 
quite sure it's compile-time configurable, but that would mean we need 
to recompile it whenever (re)installing plugins, which would be very 
uncomfortable.

The typical solution would be a wrapper that sets the path (like for 
firefox), perhaps via an environment variable. I don't know if 
xfce4-panel supports that, but it shouldn't be too difficult to patch 
it. According to [gtk] it might work by setting GTK_PATH.

Even better, maybe it would suffice to modify the desktop file entry 
X-XFCE-Module-Path or X-XFCE-Exec (see [xfce]).


Thanks for looking into it, it was also on my ever-growing ToDo list.
