# graphicsmagick's 'convert -channel' has no Alpha support, bug #352282
# ldoc is used by invoking its executable, hence no need for LUA_SINGLE_USEDEP.
# On the other hand, it means that we should explicitly depend on a version
# migrated to Lua eclasses so that during the upgrade from unslotted
# to slotted dev-lang/lua, the package manager knows to emerge migrated
# ldoc before migrated awesome.
