Tx David, for the hint.
Indeed, this seems to be what I'm looking for.
Alas, in ubuntu 8.10 x96_64 clam, annotator, etc. neither are in the 
genuine repos nor installable from the developer's link as 3rd party repo.
So I tried to compile them from sources.
I'm not experienced with this, especially not with scons.
There was an error  whith the not available dependency libxerces27-dev, 
which must be replaced by an actual one.
Compiled with a lot of warnings, nevertheless installed successfully and 
even managed to build debs.
When I'm trying to run Annotator: "error while loading shared libraries: cannot open shared object file: No such file or 
directory", even so it's present in /usr/local/lib.
I'm at the end of my rope, think I have to learn more about structures 
of system file localisation in different distributions.
Is there anybody around, who was lucky to get Clam/Annotator running? Is 
it a problem in 8.10? 64bit? Does it work in 8.04? Now I don't want to 
give up half the way.
