In order to make your use conditional, you need to wrap it, and the if condition, in a BEGIN block. This will then get run at compile time (use time). 

BEGIN {
    if ( $online == 1 ) { # This variable is defined before, according
+ to the $^0
        use POSIX 'locale_h';
        setlocale( LC_ALL, "pt_BR.iso88591" );
    }
}

My friends all rate Windows, I must disagree.
Your powers of persuasion will set them all free,
So oh Lord, won’t you burn me a Knoppix CD ?
