Bad Exit status error

On trying to build an rpm from--
http://apt.sw.be/redhat/9/en/i386/SRPMS.dag/windowmaker-0.91.0-1.rf.src.rpm,
I get the following error messages:

gcc -DHAVE_CONFIG_H -I. -I. -I../src -I../wrlib -I../WINGs -I/usr/include  -

RPM build errors:
    user dag does not exist - using root

    group dag does not exist - using root
    Bad exit status from /var/tmp/rpm-tmp.2377 (%build)

The "error: Bad exit status from /var/tmp/rpm-tmp.2377 (%build)" seems to be 
the critical fault. The srpm is a DAG build. It's supposed to work for RedHat9, 
which I'm using.

I'm wondering if his spec file might be the problem. Any hints as to what might 
be wrong?
