[Asterisk-Users] Asterisk 1.0.7 on Gentoo

[Waldo Rubinstein]

I installed Asterisk on Gentoo using emerge. At first, emerge tried  
installing version 0.9 but reading the wiki showed how to get the  
latest stable. I'm running Gentoo kernel 2.6.11-gentoo-r9.

Asterisk seems to be working just fine, but I'm concerned that since  
I don't have any Digium hardware, I may need a timer source. When I  
executed emerge zaptel, it installed zaptel 1.0.7 as well. The  
problem is that I can't seem to be able to load ztdummy or any zaptel  
module.

When I type modprobe ztdummy, I get:

# modprobe ztdummy

WARNING: Error inserting zaptel (/lib/modules/2.6.11-gentoo-r9/misc/ 
zaptel.ko): Unknown symbol in module, or unknown parameter (see dmesg)
FATAL: Error inserting ztdummy (/lib/modules/2.6.11-gentoo-r9/misc/

Can anyone help me? Do I really need or is it recommended to get a  
timer? I do need to be able to play MOH as well as have several  
MeetMe rooms. Can anyone tell me what I'm doing wrong? Could it be  
something that I need to compile into the kernel (may be I disabled a  
feature)? Could it be a setting in /etc/make.conf? I'm relatively new  
to Gentoo so I don't have much experience to tell me if it's a  
distribution issue or an asterisk/zaptel issue.

Thanks,
Waldo
