Comment(by dd32):

 {{{
 Plugin could not be activated because it triggered a fatal error. Fatal
 error: Cannot redeclare wp_new_user_notification() (previously declared in
 /some/path/wp-includes/pluggable.php:1100) in /some/path/wp-
 content/plugins/plugin/plugin.php on line xxx
 }}}

 Deactivate all other plugins, and try again.

 As long as your plugin file has the function in the global scope when its
 included, that error shouldnt occur. I think theres 1 or 2 dodgy plugins
 which do a include_once('pluggables.php'); when they shouldnt (see #9826)

 But yes, You're right, There needs to be better support for this sort of
 thing, Pluggables shouldn't be EVER used, and instead, Filters should be
 used.. (I only say that, since Pluggable functions, like you've mentioned,
 can only be replaced once..)

 See #8833 for a new direction of pluggables

 Probably should close this as a dupe of that. (Because you're original
 problem is invalid, but the idea to change the rest of it is elsewhere)
