Error: error loading precompiled runner: runner: bad binary format (version mismatch) #622
Description
Lsyncd started to give me error in subj after recent update on Arch linux.
During compilation everything seems ok. Lua is found in version 5.4 (I applied patch from PR #568 too).

Result binary looks fine, linked to correct libraries. Lua versions are same.

There is discussion at https://aur.archlinux.org/packages/lsyncd/ about this issue. Looks like multiple Lua version at system may be the problem. Unfortunately I'm not able to uninstall other lua versions as I need programs depending on older ones too :(
