Sorry about that guys. Mozilla Thunderbird for Linux doesn't let you 
"Send Again" like Eudora can. It also doesn't let you edit
messages you
forward. I meant to send this to this but Thunderbird chose to send it 
to the person directly.

Anyways, is there any problems with my compile options? I still feel 
like I'm missing something, albeit minor, crucial to the normal 
operation of Asterisk.
