Hello Enrico,
the simplest way on Windows and Mac is to silly download the following binaries and unpack their contents into a single directory

Windows:
https://github.com/LuaDist/librs232/tree/1.0.3-Windows-x86
https://github.com/LuaDist/lua/tree/5.1.5-Windows-x86

Mac:
https://github.com/LuaDist/librs232/tree/1.0.3-Darwin-x86_64
https://github.com/LuaDist/lua/tree/5.1.5-Darwin-x86_64

Downloading the “batteries" from luadist.org would also work, however there is a bug in the Windows binary which renders librs232 unusable so you would have to update the package on windows with the following commands

luadist remove librs232
luadist install librs232

Linux:

On linux the recommended way is to simply bootstrap LuaDist using the following one-liner:

echo "$(curl -fksSL https://tinyurl.com/luadist)" | bash

LuaDist itself is lua-5.2.3 based so to get lua-5.1.5 and librs232 we need to use it to install into separate directory, e.g. into “_tutorial"

./LuaDist/bin/luadist _tutorial install librs232

Once installed you can use _tutorial/bin/lua as usual.

Sorry, no magic “install” button .. yet.
