Yep. Tried it first. As much as I love Debian package system + repos, 
this package is badly outdated and broken. At least on 64-bit Etch/Xeon 
combo which I use. Not a single example from tutorial could be compiled 
by packaged stap (0.0.20061028-2), not even "hello world"!

% stap -v -v hw.stp

I got better results on my home Athlon/Kubuntu with hand-compiled kernel.

I have them all.

Exactly. :-) Looks like somebody made a typo in autoconf/other build 
stuff files.

Thanks for suggestion!

That's exactly what I followed first... to the letter.
