GRUB install problem with latest Wheezy weekly DVD

[Artifex Maximus <artifexor@gmail.com>]

Hello!

I try to install Wheezy with latest install DVD snapshot (20111011)
and when installer try to install grub it failed with "grub-pc package
failed to install into /target/". I switch to terminal four and the
log says:

"Package grub-pc is not available, but is referred to by another package.
...
Package grub-pc has no installation candidate
...
grub-installer: info: Calling apt-install grub-pc failed"

Any idea how to solve this problem? The system is a x86_64 system with
4 gigs of memory.

Thanks,
a
