srpm build error

[Athiqur Rahman]

I am trying to build freeradius rpm by following the instructions at 
http://wiki.freeradius.org/Red_Hat_FAQ#How_to_build_an_SRPM

I however get the follwing errors at the fist step

# rpm -ivh freeradius-2.1.7-7.fc12.src.rpm
  1:freeradius             warning: user mockbuild does not exist - 
using root
warning: group mockbuild does not exist - using root
########################################### [100%]
error: unpacking of archive failed on file 
/usr/src/redhat/SOURCES/freeradius-logrotate;4be01a23: cpio: MD5 sum 
mismatch

I did a rpm -K which shows

# rpm -K freeradius-2.1.7-7.fc12.src.rpm
freeradius-2.1.7-7.fc12.src.rpm: sha1 md5 OK


I installed all the rpm-build packages before hand so do not know why 
this is happening. I am using Centos 5.4
