Fatal Error: Could not open /lib/modules/2.6.15.7-ubuntu1/modules.dep.temp

Binary package hint: linux-source-2.6.15

Hello,

I have installed ubuntu linux 2.6.15-27-386 successfully. I have downloaded linux-source-2.6.15 and I am trying to rebuild the kernel from the source based on the information available at http://fossil.wpi.edu/docs/howto_build_kernel.html. After trying the following commands I am not able to boot from the kernel I built when I select the grub menu item "Ubuntu, kernel linux-source-2.6.15". The error message is:

Fatal Error: Could not open /lib/modules/2.6.15.7-ubuntu1/modules.dep.temp

I have verified the files and directoy listed in /boot/grub/menu.lst do exist, as shown below. Even if I copy modules.dep to modules.dep.temp, it is not booting.

Any idea what step I am missing?

Thanks and regards
