building rpms from source rpm's

I am getting the following error:
error: parse error in expression
error: /usr/src/redhat/SPECS/postgresql-7.4.2-1PGDG.spec:98:
parseExpressionBoolean returns -1
error: Package has no %description: postgresql

When I execute 

rpmbuild --rebuild  --define 'build9x 1' --define 'tcldevel 0' --define
'perl 0' --define 'tcl 0' --define 'tkpkg 0' --define 'test 0' --define
'newintarray 1' --define 'kerberos 0' -vv  SRPMS/postgresql-7.4.2-1PGDG.src.rpm
