Starting with windowlab 1.32 the sample menu file in the sources has been renamed from menurc.sample to windowlab.menurc.
Created attachment 95687 [details, diff] Renamed menufile patch for windowlab-1.32.ebuild
Created attachment 95692 [details, diff] New Menufile name Sorry, bit unconcentrated today. This diff now installs the menurc file with the correct name.
Fixed in CVS, thanks for reporting!
