package fglrx 2:8.723.1-0ubuntu4 failed to install/upgrade: fglrx kernel module failed to build

  $ ubuntu-bug -p fglrx-installer

The package simply doesn't install, there is an error.
Moreover, the proprietary driver for the ATI card is even not being shown in Jockey.
I'm using Ubuntu Maverick Beta, on a Sony Vaio, with a ATI Radeon card.
