There is no cool command unfortunately.  I use a cron script like this to remove oldest files first:

#!/bin/sh
set -e
. /etc/sysconfig/dnscap

cd `dirname ${DNSCAP_BASEPATH}`
while sleep 1 ; do
	GB_FREE=`df -B 1G . | awk 'NR==2 {print $4}'`
	echo $GB_FREE GB free | logger
	test $GB_FREE -gt ${DNSCAP_FREE_GB} && break;
	ls -rt | grep '^dnscap\.' | head -n 1 | xargs rm -v 2>&1 | logger
done
