ok,
i solved this on my own:
pstotext seems not to work without ghostscript
but pdftotext does not need ghostscript.
here you can download source and precompiled
binaries from pdftotext:
http://www.foolabs.com/xpdf/download.html
x86, Linux (glibc 2.2, staticly linked to Motif, t1lib, and FreeType 2): xpdf-3.00-linux.tar.gz (4544077 bytes)
just download the xpdf package - untar - and upload the
pdftotext file via ftp
hope it helps others
tomas
