blackout24 [1] filed a deletion request for valgrind-mmt [2]: I'm maintainer of this package. Unfortunately I forgot to indicate this as a development package (-git) in the package name. The right package is valgrind-mmt-git. [1] https://aur.archlinux.org/account/blackout24/ [2] https://aur.archlinux.org/pkgbase/valgrind-mmt/
