Using Lua 5.1.5

On Rocky Linux 8.7

• Linux uhn5klbjhmgmt-p.lab.rmn.local 4.18.0-425.10.1.el8_7.x86_64 #1 SMP Thu Jan 12 16:32:13 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

Luarocks compiles and installs it with no problem :

However when issuing a require on it it fail:

My bad . closing it was the fault of #!/usr/bin/lua instead of #!/usr/bin/env lua , thus not using my luaver env but the default system lua!
