MailCall and PHP issues - Nerd vittles

Hello I am a complete Asterisk Newbie.

I have asterisk up and running on a dedicated server.
I am running Fedora Core 5
Asterisk from source

I think this is really just a linux issue, but I will try it here as it is asterisk related. flite my TTS is working fine but I get an error when the script tries to call /usr/lib/php/modules/ I have googled it a dozen diffrent ways, and cant find what would cause this error. I thought It would be an imap issue, but this seems to be loaded fine.

IMAP c-Client Version 2004

From Asterisk
Executing Hangup(“SIP/”, “”) in new stack
== Spawn extension (FUN, 555, 10) exited non-zero on ‘SIP/’
No such command ‘/var/lib/asterisk/agi-bin/nv-mailcall.php’ (type ‘help’ for help)

Thanks for any help or direction you can give me.
