[arch-general] Build from source question.

Good day. I'm going to compile all needed packages for archlinux. There are many source mirrors at the net not only URLs from PKGBUILD. Usually it is "distfiles" dir from gentoo or freebsd. It contains sources for their ports. I want use this sources. How can I to make makepkg to look for source in my LAN mirrirs to get it first from there and only then from PKGBUILD's url ? For example in CRUX pkgmk.conf there is PKGMK_SOURCE_MIRRORS=(...) wich point to list of such mirrors. I looking for the same in archlinux. -- Anton [WARM-RIPE] Stack ltd division head tel. 8 (3822) 555-797
