Hi again. I had now some time and did the tracing with Strace:

I got heaps of output but I cant really figure out what it means:

Anyone an idea whats going wrong?

I also tried ltrace but it wont work:
/chi@chi: ltrace -f mathematica
"/usr/local/bin/mathematica" is not an ELF file/

A guy from the gentoo forum meant that I should put this in my make.conf
and recompile:
ABI_X86="64 32"
It also did not help at all. ;(
