RPM error on kernel source update (2.4.20-18.9) ?

["Brad Alpert" <BAlpert@xxxxxxxxxxxxxxxx>]

Anybody else get this error on the kernel source update, or have I
missed a relevant thread?

The binary unpacks and installs fine, just the error on the sources,
which I downloaded from RH's updates site.
