I don't have any dependences remaining you misinterpreted something.

In the first time I needed some way to handle pdf files I had to connect to a linux machine in my network where the conversion from pdf to ps was done by using command line tools. The result of this conversion were first jpeg files afterwards svg files for which I wrote a renderer in plan9. The second step was to write a converter pdftosvg which works for pdf files I had to handle. No C++ no postscript interpreter. If you have to handle pdf files with embedded postscript than I wish you good luck.
