There's probably a LuaRocks package you can ask the administrator to
install (should be available basically everywhere where there's a
package manager, plus Windows), and then you write `luarocks install
--local penlight` and you'll have a copy of Penlight installed in your
home directory.

Running `eval $(luarocks path)` will fixup your package.path so that
the necessary directories are included. (There's also `eval $(luarocks
path --bin)` if you want to modify your $PATH to include any scripts
installed via LuaRocks.)
