rafaelff [1] filed a deletion request for gstreamer0.10-mm [2]: Doesn't build anymore with latest icu, I haven't found a fix for this incompatibility, and no one seems to care (3 years without a package update).
FYI, search "error" in the build output: http://ix.io/2xFP [1] https://aur.archlinux.org/account/rafaelff/ [2] https://aur.archlinux.org/pkgbase/gstreamer0.10-mm/
