gimp-devel-source http://aur.archlinux.org/packages.php?ID=31926 looks almost the same as http://repos.archlinux.org/wsvn/packages/gimp-devel/repos/extra-i686/PKGBUILDone difference I seen was in gimp-devel-source at the ./configure line --disable-devel-docs seems to be about the same in my opinion.
