The difficulty is that, for each package with a line like: Architecture: $arch $arch $arch If $arch is not "all"/"any", in order to tell if the package is built for the current architecture, debhelper must run 'dpkg-architecture -amipsel -i$arch' for each listed architecture to see if it matches. Because $arch could be "linux-any", it can't just stringwise compare to see if $arch = mipsel. For gcc-4.4, there are 190 such $arches mentioned in its control file. Wow. If I memoize that, it'll still need one dpkg-architecture call per unique $arch mentioned in the control file. Which at least will reduce the number to 13 for gcc-4.4. (Plus do stringwise compare first, which will drop it to 12.) If I could assume that any $arch without a dash in it is certianly a real architecture, and not linux-any or some such thing, I could further reduce it to 1 call, for kfreebsd-amd64. Depends how much knowledge about architecure wildcards I want to put in debhelper. If dpkg-architecture had a better interface, debhelper could call it just once. Imagine: dpkg-architecture -amipsel -i"$arch $arch $arch" (Using the new Dpkg::Arch perl module could be a better approach later.) -- see shy jo
