[wp-hackers] wp_die vs hooking into admin_notices

[fris]

Curious what would be the best way.

register_activation_hook(__FILE__,'curl_check');

function curl_notice() {   
	echo '<div id="my-custom-warning" class="error fade"><p>This plugin
requires CURL.</p></div>';   
} 

function curl_check(){
	if (!function_exists('curl_init')) {
		deactivate_plugins(basename(__FILE__)); 
		add_action('admin_notices','curl_notice'); 
		//wp_die("Sorry, but this plugin requires CURL.");
	}
}

wp_dir or hook a function into admin_notices?
