Building can't find `lua_objlen`

[Kimapr]

My OS is GuixSD. After updating my guix profile minetest stopped working.
now trying to re-build minetest fails with this:

Code: Select all

(solved)
lua versions mismatch, even when i said it to use luajit, it uses lua 2.3 installed on my guix profile
fixed by downgrading it to lua 5.1
