# 3.22.5+ *does* support GRASS 8 but we can't enable it yet because of
# https://github.com/OSGeo/grass/pull/2269 (=> unresolved SONAME dependencies)
# Keep an eye on that bug / a fixed GRASS release and readd support
# by unrestricting the dep in ${COMMON_DEPEND} once it's fixed!
# (No need to change the supported GRASS versions in src_configure b/c
# it won't find GRASS 8 with this dependency set.)
