_d_arraysetlength2 should be defined in the new libphobos.a. Make sure the new one is installed over the old one.

I can't replicate this issue. Did you rebuild Phobos or are you trying to use GDC's GPhobos in combination with DMD?

Ah, I had forgotten about libphobos.a in /usr/lib.  Indeed, this was the cause.

Thank you.
