So... what's the exact error? And how quickly are you doing this? There is a delay between the arch dev machine that the developers use and ftp.archlinux.org (about 5-15 minutes IIRC)
Do you mean that ftp.archlinux.org synchronizes with dev machine? I do $ svnsync --non-interactive sync file://localhost//srv/base-repos.svn $ svn up # from locally synced mirror svnsync works with svn://svn.archlinux.org or with svn+ssh://aur.archlinux.org for community. So I think I get freshest PKGBUILDs. then I iterate all of repos/ subdirs and try to do makepkg --allsource. Generally error is 'file not found' for packages which use ftp.archlinux.org in sources array. For example texlive-core-doc: $ makepkg --allsource ==> Making package: texlive-core-doc 2008.13013-1 x86_64 (Пнд Окт 5 20:41:41 MSD 2009) ==> Retrieving Sources... -> Downloading texlive-core-doc-src.zip... --2009-10-05 20:41:41-- ftp://ftp.archlinux.org/other/texlive/texlive-core-doc-src.zip => “texlive-core-doc-src.zip.part” Resolving ftp.archlinux.org... 209.85.41.144, 209.85.41.143 Connecting to ftp.archlinux.org|209.85.41.144|:21... connected.
