Using systemtap

Hi,

I want to use systemtap and installed rpm's
systemtap-0.9.7-5.el5
systemtap-runtime-0.9.7-5.el5
kernel-debuginfo-common-2.6.18-164.el5.x86_64.rpm
kernel-debuginfo-2.6.18-164.el5.x86_64.rpm

I cannot find the correct kernel-devel rpm.

uname -a gives as kernel 2.6.18-164.0.0.0.1

I have the following questions:
1.Did I install the correct rpm's?
2.Where can I find the correct kernel-devel?
3.Can it be omitted?
4.
When running script probe kernel.function("*") {}
I get the errors below:
Pass 1: parsed user script and 52 library script(s) in
250usr/0sys/265real ms.
semantic error: libdwfl failure (missing x86_64 kernel/module debuginfo
under '/lib/modules/2.6.18-164.0.0.0.1.el5xen/build'): No such file or
directory while resolving probe point kernel.function("*")
semantic error: no probes found
Pass 2: analyzed script: 0 probe(s), 0 function(s), 0 embed(s), 0
global(s) in 0usr/0sys/6real ms.
Pass 2: analysis failed.  Try again with another '--vp 01' option.

Is that due to the missing kernel-devel package or is something else
wrong?

Regards Hans
