[elrepo] help with trying to make a 4.9 LT based on the 4.4LT spec file

[Jerry Scharf]

Hi,

I am hoping to get help with this. I have been using el-repo rpms to 
install the 4.4lt kernels.

4.9 introduced BBF tcp congestion avoidance, which is a major 
improvement and will have a real positive impact on our traffic. The 
kernel.org folks have designated 4.9 as the next lt kernel after 4.4. So 
I want to get that running similar to el-repo 4.4 works now.

I copied the 4.4 spec file, modified it for 4.9. I grabbed 4.9.31 from 
kernel.org, unpacked it and built a new config file starting with the 
4.4.71 config plus my few changes. On the same machine, 4.4.71 builds 
successfully.

I tried rpmbuild -bb and it made it most of the way through before dying.

It fails with:
File not found: 
/root/rpmbuild/BUILDROOT/kernel-lt-4.9.31-1.el7.centos.x86_64/usr/lib64/libcpupower.so.0.0.0

find finds it numbered as 0.0.1 and not 0.0.0

find ../BUILDROOT/ -name libcpupower.so\*
../BUILDROOT/kernel-lt-4.9.31-1.el7.centos.x86_64/usr/lib64/libcpupower.so.0
../BUILDROOT/kernel-lt-4.9.31-1.el7.centos.x86_64/usr/lib64/libcpupower.so.0.0.1
../BUILDROOT/kernel-lt-4.9.31-1.el7.centos.x86_64/usr/lib64/libcpupower.so


file libcpupower.so.0
libcpupower.so.0: symbolic link to `libcpupower.so.0.0.1'

Why is this different and why is it dying? It only asks for 
libcpupower.0 in the requires file and that is there.

thanks in advance,
jerry

here is the last part of the build log before it dies:
