Setup Failed To Build Kernel Modules

[eugenevdm]

OS: Fedora Code 4 64-bit

Acronis True Image Server Setup failed to build kernel modules. Consult /var/log/trueimage-setup.log and /var/lib/dkms/snapapi26/0.7.10/build/make.log for error messages.

Consulted HOWTO.INSTALL and this forum.

HOWTO.INSTALL has no specific information for Fedora Core 4 64-bit but quite a lot of detail on dkms.

[root@cp1 boot]# /usr/sbin/dkms build -m snapapi26 -v 0.7.10 --config /boot/config-2.6.11-1.1369_FC4 --arch x86_64 --kernelsourcedir /usr/src/redhat/

Error! Your kernel source for kernel 2.6.11-1.1369_FC4 cannot be found at
/lib/modules/2.6.11-1.1369_FC4/build or /lib/modules/2.6.11-1.1369_FC4/source.

Prior to that I download and installed:
kernel-2.6.11-1.1369_FC4 Source RPM
From Fedora Core 4 Sources
at:
http://fr.rpmfind.net//linux/RPM/fedora/4/src/kernel-2.6.11-1.1369_FC4.src.html

But it looks like I'm still missing something. Please help!
