Oh, and if you try secondlife PKGBUILD I sent, please note that we have distcc (pacman -Sy distcc), so you could get much faster results using this and removing DISTCC=no. Also FMod and x86_64 are said to not work together. Anyway, the SConstruct file (some kind of Makefile in Python) does deactivate FMod on x86_64. But of course, avoiding to touch these PKGBUILDs could help you very much keep your mental sanity.
