Closed issue by huglovefan on void-packages repository

https://github.com/void-linux/void-packages/issues/25396

Description:
* xuname: `Void 5.8.10_1 x86_64 GenuineIntel uptodate rrrmdFFF`
* package: `luarocks-lua51-3.3.1_3`, `luarocks-lua52-3.3.1_3`, `luarocks-lua54-3.3.1_3`

luarocks comes with some lua modules, but currently they're only installable for lua 5.3

one is documented to exist here:

>
> Alternatively, you can load the LuaRocks module loader from Lua by issuing this command:
> ```
> require "luarocks.loader"
> ```
> If your system is correctly set up so that this command runs with no errors, subsequent calls to `require()` are LuaRocks-aware [...]

but this only works with lua 5.3 in void

reproduction steps:

```sh
xbps-query -Rf luarocks-lua51 | grep /usr/share/lua/5.1/
xbps-query -Rf luarocks-lua52 | grep /usr/share/lua/5.2/
xbps-query -Rf luarocks-lua53 | grep /usr/share/lua/5.3/ # only this one outputs anything
xbps-query -Rf luarocks-lua54 | grep /usr/share/lua/5.4/

xbps-install luarocks-lua52
luarocks-5.2 --local install dkjson # <-- installs to ~/.luarocks
lua52 -e 'require("luarocks.loader") require("dkjson") print("success")' # <-- succeeds with 5.3 only
```

at least debian seems to include the same modules for all lua versions in the luarocks package: https://packages.debian.org/sid/all/luarocks/filelist
