Ok, I know what's wrong in this case. I had changed include/lalloca.h
because the sender of the SCSI patch wrote that it causes problems on
MacOS X. So please try to change the following line:

#if defined(__GNUC__) && !defined(HAVE_NSLINKMODULE)

back to

#if defined(__GNUC__)

What's the problem with the link order?
