Huh, that's an error that I haven't seen before. I'm not really sure
what's causing this, so I'll just suggest the general ConTeXt
troubleshooting techniques.

First, make sure that all of the binaries are pointing at the same
things. All of the following should give the same output

    $ realpath $(type -p luametatex)
    $ realpath $(type -p context)
    $ realpath $(type -p mtxrun)

(replace "realpath" with the equivalent BSDism for resolving a symlink)

Then, remove any previously-built format files:

    $ rm -r $(kpsewhich --expand-var='$TEXMFVAR')/{luametatex,luatex}-cache/
    $ doas rm -r $(kpsewhich --expand-var='$TEXMFSYSVAR')/{luametatex,luatex}-cache/

Then generate the base interface files as root (you'll only ever need to
do this once):

    $ doas luatex --luaonly $(kpsewhich --format=texmfscripts mtxrun.lua) --luatex --generate

Then build the interface and format files as a regular user:

    $ mtxrun --generate
    $ mtxrun --luatex --generate
    $ context --make en
    $ context --luatex --make en

Pay close attention to the output of "context --make en"; if the end of
the output doesn't look something like the following:

    resolvers       | formats |
    system          | total runtime: 3.959 seconds of 4.086 seconds

then something probably went wrong. After you've done all of this, you
should be able to run the following without any error:

    $ context --nofile

(you can replace the above command with a simple "hello world" document
if you prefer).

Hopefully all of this fixes the problem, but if not, at least knowing
which step failed should help to narrow it down.

"texexec" -> MkII
"context --luatex" -> MkIV
"context" -> MkXL/LMTX

(correct otherwise though)
