Hello,

you should make

tex/texmf-openbsd7.3-amd64

and put 5 files there:

luametatex context -> luametatex mtxrun -> luametatex mtxrun.lua context.lua

Thanks for your hints. I did as you said but got stucked with a tree structure problem. Since I was lacking the time to dig into it, and a new update was announced, I simply loaded the new binary from pragma. But I now understand the workflow to update to 7.4: update to the latest lmtx (I do not update so often), ugrade OBSD, build the new binary if no upload is available. Anyway, 7.3 binaries work ok. Many thanks! Damien T
