Dlsym: tcb not found

i finally managed to compile redox-os.
i can “make qemu” and the vm starts, asking for screen-resolution, GUI coming up. But when i login:
redox login: root
password:
Welcome to Redox OS!

dlsym(0x0, pipe2)
dlsym: tcb not found

and then a shell-prompt. The shell looks like it is working.
I assume dlsym is something linker-related not finding some binary-libfile or missing symbols in it.

Does somebody have a hint where to look next for the problem-cause?
