These instructions are gold, thank you. You should capture them somewhere in some instructions.
I hit one other snag, which was the "switch create" step wanted me to have something called bubblewrap, or bwrap (which was a pleasant distraction, because I had to try all my package-manager commands with both "bubblewrap" and "bwrap"—luckily none of those worked anyway). I followed these instructions to get out of it: https://github.com/ocaml/opam/issues/3424#issuecomment-450786508 Also, on an Ubuntu 14.04 machine, I hit an error during the links build which was a C error in the ssl package. Presumably some version mismatch. I'm not too fussed about that, but I'll post my error in another message for completeness. Thanks for your quick help!
