Dear Jörg,

the libraries were really there, but anyway your comment made me
realise that my path settings of my libraries weren't correct.  I
corrected it and now it works.  I didn't fully realise that the libstdc
++ actually needed a path... I thought just including the necessary
libraries in the arch-file would be enough...

thanks a lot for your help
cheers!

marc
