thanks @gliptak, give me some time to take a closer look, building from these is still manual my side :-)

hi @gliptak sorry for delay. I had a quick quick look locally and when doing cd scripts && ./build-base-dependencies-alpine-image.sh it fails with the issue below. I think we may need to do a more recent image compatible with opam, but that's just a guess. I'll try investigate further tomorrow.
