As Ben said in the other reply. Why not just use syslog? I do this in 
/etc/syslog.conf:

At the top of the file above all the other lines:
!-dhcpd

...

At the bottom of the file below all the other lines:
!dhcpd
*.*                                             /var/log/dhcpd.log
!*

This will cause all log lines from dhcpd to go to that file and remove 
them from all of the other files.

And then something like this in /etc/newsyslog.conf:

/var/log/dhcpd.log                                      640 3 * $W6D0

Which will rotate it every week.
