For your first qustion; when you use LuaRocks to install a package
while you aren't root, the package will get installed in
/home/<my_user>/.luarocks/ instead of /usr/local/ and become only
available for you. Moreover Lua doesn't know with its default setup that
packages can be available in the current user's home. If you want to
install a package available for all user, you should run as a sudoers.
For your second question, it looks to me like a misconfiguration of the
stdlib package since those files does not have the correct permissions.
You should at least set them to readable for all users (chmod a+r or
chmod 644).
Thomas.
