thank you very much for your attention, Andras has sent me the description
of the easy way:

 automake --foreign -a

and it worked (despite of the graphic-distiller). duster is compiled.

I have tested duster with different more ore less dusty (and hairy, 
because of the cats here around ;-) ) slides, but I see no big difference
in the output of duster and the original rgb-scan. This ist contradictionary
to the log of duster:

Reading IR file... done.
Reading RGB file... done.
Combining files into one array... done.
Cleaning image... done.
Replaced 5728 of 6747 obscured pixels.
Writing output file... done.

Maybe i'm making some mistakes in the scanning process.

btw: The output couldn't  be opened with gimp (1.2.3). 
Message of the gimp: x-resolution is wrong.

After convert in.pnm out.pnm gimp was satisfied ;-) .

thank you all,
