Have a conflict w/ BuddPress friends online plugin, and the BuddyPress Multi Network plugins

Get this error code when using the two together.

http://wordpress.org/plugins/buddypress-friends-on-line/

I do not get the error on the main site, but all sub sites do produce it. Just a blank page and the following error.
Fatal error: Call to undefined function bp_get_friends_slug() in /home/mtbmtbco/public_html/wp-content/plugins/buddypress-friends-on-line/bp-friends-on-line.php on line 17
