Slight oversight. Thanks for the one-liner fix. Looks like we'll have to do the same thing for the following: sys/boot/ia64/common/Makefile sys/boot/powerpc/ps3/Makefile sys/boot/sparc64/loader/Makefile Here's a patch that can be applied by anyone willing: http://druidbsd.sourceforge.net/download/loader_menu-1.6.1-HEAD201105210929= 52-fixup.patch --=20 Devin _____________ The information contained in this message is proprietary and/or confidentia= l.
