I only recompiled package from the ArchLinux (x86) PKGBUILD files, using
makepkg -a and installing missing dependencies with pacman.
You can find my ArchlinuARM compiled packages here, I will try to understand the process to integrate them in ArchlinuxARM AUR.
I put them in my Cubieboard directory, but there should work fine for any ARMv7h plateform where ArchLinuxARM runs :
To install a package from filesystem :
pacman -U name_of_the_package.pkg.tar.xz
