error: bind-9.5.0-25.1.b2.fc8.src.rpm cannot be installed

[Agnello George]

i am trying to install bind-9.5 src rpm  on my centOS system !!
i get the the following error :
the source for this is http://people.redhat.com/atkac/bind/

[root at rhel5 src]# rpm -ivh bind-9.5.0-25.1.b2.fc8.src.rpm
error: bind-9.5.0-25.1.b2.fc8.src.rpm: Header SHA1 digest: BAD
Expected(17fdf6bc865e18049b5b676cd033278d6315c2ce) !=
(d8bc2f1f6b9fec9fc5913627ab017e371026d58d)
error: bind-9.5.0-25.1.b2.fc8.src.rpm cannot be installed


if your wondering why i am using the src rpm is cause i would have to
edit the bind.spec file

i don't understand what  Header SHA1 digest: BAD Expected means ??

can any one help me out here !!!

thanks
