[tex-live] TL2018/LuaTeX/Mac "bug" (but also probably in all other distributions as well)

I'm not aware of anyone attempting to fix
    source/aclocal.m4
so far. If you contribute the patch for that, this will be the best
and most lost-term future-proof solution :)

Only if Dick uses
    export STRIP="strip -u -r"
when he builds the binaries.

Since you are in the testing mode right now: can you please do me a
favour and test the luatex binary from x86_64-darwinlegacy to confirm
whether that one works as expected? (You can get it in the subversion
repository of texlive or on the tlpretest repository, but it needs to
be extracted manually or you would need to install an additional
platform.)

Thank you,
    Mojca

For example the sqlite3 bindings from http://luaforge.net/projects/luasqlite/ [^] create a library on OS X that require the symbol _luaL_argerror to be defined in the LuaTeX binary:
