thats most likely because you cannot call $cfg->vars() if your Config::Simple object could not be created (although, the error message doesn't match to your example code).

You should check for and handle the error on the line you create the Config::Simple object (no later): 
my $cfg = new Config::Simple($config_file) or die "aaarg $!";
