Run (assuming Mathematica command runs it):

$ strace -ff Mathematica -o mathematica
(install dev-util/strace if you don't have it)

And look through all mathematica.$pid files. They will contain
every system call. You will be able to see what files application
tries to access, what network actions it tries to perform and so
on. The answer will be there, but it will not be very easy to find.

A good start will be to grep trough all file and socket access (or
use -e filter of strace itself). Maybe it tries to load some
library, or to run some tool and fails. Maybe required component is
present on your system, but version is different from what is
needed.

8) As a complementary to strace you may use dev-util/ltrace. ltrace
will print you *each* library call made buy an application. Output
data will be enormous, but will contain a very detail fingerprint
of what application does. With some effort this should help to
understand what is wrong.

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. ;(
