The kernel fails to install when running rpm -ivh
Error message is
2: kernel
E: failed to install /usr/lib/python 2.6/site packages/bitfrost/__init__.py
mkinitrd failed
warning:%post(kernel-2.6.32-0.48.rc7.git1.fc13.x86_64) scriptlet failed, exit status 1

In the process, all kernel entries in grub were removed: Only Windows XP was showing.

This is an update to a Fedora 12 system: all other "fc.13" changes (from rawhide) were accepted and worked. (Kernel was the last to be installed --- resulting the above error.)

rpm -qa shows two kernels (the above kernel & fc12 --  latest version) as being installed.

What needs to be done to make the system functional?

TIA
