Yes, use lua_pcall if you need to catch errors when calling lua code.
(Actually I think it is better to say: "use lua_call only if you don't
need to catch errors, that is if you are in a C-function called
from pcalled Lua-code")

lauxlib contains lua_dofile which is there for 4.0 compatibility (I guess),
It also does call global function _ALERT on errors.
