asterisk users - Nov 2005 - Zaptel: Hz != 1000 causing ztdummy compilation error?

Hi all,

When I compile zaptel from today's cvs HEAD on an updated FC4 box it
fails with the following message:

  CC [M]  /home/patrick/redhat/BUILD/zaptel/ztdummy.o
/home/patrick/redhat/BUILD/zaptel/ztdummy.c:103:2: error: #error ztdummy
requires 1000 hz jiffies

If I comment out the code causing that error the compilation goes fine
but I guess it's there for a reason :) After some googling I tried the
following but that did not solve the issue:
echo 1000 > /proc/sys/dev/rtc/max-user-freq
compile still fails
echo 1024 > /proc/sys/dev/rtc/max-user-freq
compile also fails

Anyone have a pointer how I solve this error?

Thanks and regards,
Patrick
