Freeradius-client in pppd

I need the feature to specify the local ip address for the radius requests in PPPd and I see that freeradius-client-1.1.5 has that feature. Is there any patch to make pppd use this radius client instead of it's own copy of the old radiusclient? -- damjan | дамјан This is my jabber ID --> damjan@bagra.net.mk -- not my mail address, it's a Jabber ID --^ :)
