This is the port of pavispanel for gnome-panel to XFCE panel. The compiling method is the same as for gnome-panel. Goto the source directory and execute ‘make’ there to compile and ‘make install’ to install. For most Linux systems the packaged binary will be able to run without any trouble the binary is compiled on Lucid(Ubuntu 10.04)
PS: If you can make a auto tools source package for this please make one and send to email@example.com or comment here :). It is appreciated if you do so!
