[kozu@xxxxxxxxxx]

Can somebody help me?
Following Problem occurs:

--with-kernel-src=/usr/src/linux-source-2.6.18/
.
.
.
checking kernel release...
checking kernel module install path... 
NONE/lib/modules//kernel/net/ipv4/netfilter
checking for ll_cluster_new in -lhbclient... no
configure: error: ""
    "**********************************************************************"
    "* saru requires heartbeat. Available from"
    "* http://www.linux-ha.org/download/ and mirrors."

I'm using Debian/Etch(4.0) with kernel-2.6.18 and I installed Ultra Monkey 3 by 
simply typing "apt-get install ultramonkey" as guided at

http://www.ultramonkey.org/3/installation-debian.sarge.html

Does anyone know what kind of problem occured?
