Created attachment 3349 fixes underlink issues Building the plugin on a platform like Fedora Rawhide (and probably Debian or Mandriva) fails due to underlinking issues; panel-plugin does not link against (or pull CFLAGS from) xfcegui, and src does not link against (or pull CFLAGS from) xfcepanel (so it can't find headers at this stage of build). Patch is attached which fixes both of these issues, and allows the build to succeed.
fixed, thx. for reporting
