I can't build the 8.1.0 source rpm from postgresql.org

I downloaded the postgresql-8.1.0 source rpm for Fedora Core 4 from the
rpm repository at postgresql.org.

I installed the rpm with " rpm -i postgresql-8.1.0-2PGDG.src.rpm"

I then attempted to rebuild the packages with

rpmbuild --rebuild --define 'tcl 1' --define 'kerberos 0' --define
'tcldevel 1' \
--define 'pltcl 1' postgresql-8.1.0....

It appears to die in the prep stage:

Any suggestions?
