Problem is that the PS Interpreter tries to seek on the input file for certain
files. A fix would be to avoid seeking under all circumstances, for example by
reading bigger pieces into a buffer.

A workaround is to never call Ghostscript with "-" as input file but always use
"-_" instead. For this especially also all scripts which come with Ghostscript
need to be fixed. See the attached ps2pdfwr as an example. The additional

if [ "${infile}" = "-" ]; then
    infile="-_"
fi

solves the problem when any ps2pdf* script is used.
