Thank you all. First I gave the pdfpages package in use with pdflatex another try, but the creation process reported errors within 2 eps graphics. After converting them, these errors were gone, but new errors came and I lost my temper.
So I decided to do it the not-so-elegant way and splitted the 11 pages of the document in 11 postscript files which I inserted manually after all. Bye. Thorsten -- PGP public key: http://home.arcor.de/thorstenhirsch/thirschatwebde.asc
