problems building libpcap rpm ..

[Gregory Machin]

I'm getting the following errors ....
error: Name field must be present in package: (main package)
error: Version field must be present in package: (main package)
error: Release field must be present in package: (main package)
error: Summary field must be present in package: (main package)
error: Group field must be present in package: (main package)
error: License field must be present in package: (main package)

When I try to rpmbuild -ta /home/builder/rpm/SPECS/libpcap-0.8.3.spec

The source file /home/builder/rpm/SOURCES/libpcap-0.8.3.tar.gz

I have made sure that the same spec file is also in the libpcap-0.8.3.tar.gz

what have i missed  ?
