Unable to --rebuild postgresql-7.1.2-4PGDG.src.rpm

I just downloaded the src rpm for postgres 7.1.2

    postgresql-7.1.2-4PGDG.src.rpm

and tried to rebuild it:

    rpm --rebuild postgresql-7.1.2-4PGDG.src.rpm --target=i686

and got the following compile error!  (I'm compiling on RH7.1.)  Is
there anything I can do or can someone let the folks responsible for the
package know?

(Note: I was able to rebuild the 7.1.1 RPMS no prob.)
