>Description:
Currently, the buildlink3.mk files are included many times, although doing that 
once is usually enough.

>How-To-Repeat:
cd /usr/pkgsrc/graphics/gimp-refocus-it
bmake show-all-features

(This shows "glob" many times, since it is mentioned in one of the 
buildlink3.mk files. It should only be mentioned once for every package that 
requests it.)

>Fix:
Put the .include lines between the multiple-inclusion guards.
