Cython error: Lua "undeclared name not builtin: long"

[waarmond]

ArchLinux, Python 3.10, Cython 3.0.10 (0.29.36 didn't got accepted)

Error compiling Cython file:
------------------------------------------------------------
...
        args = cpython.tuple.PyTuple_New(length)
        lua.lua_pushnil(L)            # nil (first key)

lupa/lua51.pyx:752:37: undeclared name not builtin: long

I don't have lua51 installed on my system; this is the bundled version.

PS: Building 1.14.1 against cython 0.29.36 works.

Try lupa 2.1.

My source file is lupa-2.1.tar.gz (sha256 d0fd4e60ad149fe25c90530e2a0e032a42a6f0455f29ca0edb8170d6ec751c6e) from https://gitlab.archlinux.org/archlinux/packaging/packages/python-lupa

But deviating from vanilla ArchLinux I'm using an older Python version
