systemtap on fc6, syscall.open failes

[Tomas Kouba <tomas at jikos dot cz>]

Hi all,

I am trying to learn something about systemtap and I am following the 
tutorial now, but I am stuck at the second example. It seems that my 
systemtap installation on fedora core 6 is broken.
This is my session:

root@dwarf:~/systemtap

$ rpm -q kernel-debuginfo

So I think I have installed everything I should, but still have no luck.
Thanks for any help.
