Created attachment 3446 xfce4-sensors-plugin-1.0.0 compile log 1. configure initially fails to find exo and bails out. fixed by changing pkgconfig tests from exo-0.3 to exo-1 2. make then fails because the compilation can't find libxfce4panel/xfce-panel-plugin.h I attach the compile log. PS. The download links need to be updated on http://goodies.xfce.org/projects/panel-plugins/xfce4-sensors-plugin
the plugin compiles with 4.8 since a few weeks. will fix the links, thanks for reporting.
