asterisk users - Feb 2009 - 1.6.1-rc1 errors

I am getting the following warnings on the CLI when loading Asterisk
1.6.1-rc1:

[Feb 12 12:32:34] NOTICE[22261]: timing.c:59
ast_install_timing_functions: Multiple timing modules are loaded.  You
should only load one.

[Feb 12 12:32:34] ERROR[22261]: codec_dahdi.c:398 find_transcoders:
Failed to open /dev/dahdi/transcode: No such file or directory

[Feb 12 12:32:33] WARNING[22261]: chan_iax2.c:10939 build_user: Unable
to support trunking on user 'telecomab' without DAHDI timing
[Feb 12 12:32:33] WARNING[22261]: chan_iax2.c:10679 build_peer: Unable
to support trunking on peer 'telecomab' without a timing interface

	I am using DAHDI 2.1.0.4, Asterisk 1.6.1-rc1 on a CentOS 5.2 machine
with a TDM04 card.  These are the modules:

Module                  Size  Used by
dahdi_echocan_mg2       9608  0 
wctdm                  39884  4 
dahdi                 190728  2 dahdi_echocan_mg2,wctdm

	Where do I have to specify the timing module?

Timing may be provided from one of two sources in Asterisk 1.6.1: 
res_timing_dahdi.so (get timing from DAHDI), and res_timing_pthread.so (use 
pthread library for timing). There are a couple of ways to fix your problem, 
assuming that the timing module you want to use is res_timing_dahdi.so.

1) Remove res_timing_pthread.so from /usr/lib/asterisk/modules and restart
Asterisk
2) In modules.conf, add noload => res_timing_pthread.so
3) While not a requirement, you can also make menuselect and disable 
res_timing_pthread.so from being built at all. The module can be found under the
Resource Modules menu.

It looks as though the timing modules for 1.6.1 are not well-documented, and 
Menuselect should be altered to not allow for both modules to be built.
We'll
get to work getting this documented better.
