asterisk users - Nov 2013 - DAHDI Missing '/sys/bus/astribanks/drivers/xppdrv/sync'

Hello group,

I am installing Asterisk on a new pc running Ubuntu 12.04.3 Server. ?I have
dahdi-complete-2.7.0.1+2.7.0.1, and have tried 2.6.1 and 2.8.0-rc1 and
2.8.0-rc2. ?I am following along in the ASTERISK The Definitive Guide 4th
Edition and on page 116 when I issue the command $ sudo /etc/init.d/dahdi start
I get the following error:

Loading DAHDI hardware modules:
? ?wctdm24xxp: done
Running dahdi_cfg: done.
Missing '/sys/bus/astribanks/drivers/xppdrv/sync'

I found some steps
at?https://issues.asterisk.org/jira/browse/DAHLIN-325?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Here is the output of the commands listed there:

I have ran the command?dahdi_genconf system and?dahdi_genconf system modules
trying to reload dahdi each time.

Here is the output of my /etc/dahdi/system.conf file:

Hi, it's safe to ignore this message, but for future reference I
just committed a change [1] that will now prevent it from showing,
which will be in the final v2.8.0 release of DAHDI-tools.
