is that the exact error message? i think it should be "attempt to
call global 'print' (a nil value)", which means that 'print' isn't
defined, as should be expected if you haven't loaded the standard
library by skipping luaL_openlibs(L)

in short: no, it's not mandatory to call luaL_openlibs; but if you
don't then you don't get any default function, like print()
