Your post made me a bit curious but you did not say which Sabayon you are trying to install, so when I got back from a few days break I downloaded both the Gnome and KDE versions (SL5.3 amd64)
The first one I tried was Gnome, got as far as creating /boot, swap and / in custom partition layout when I would receive an error after trying to advance, so I then opened a terminal and ran gparted
In gparted I selected to create a new partition table, clicked on apply and received an error (very strange) I rebooted to live dvd and opened gparted and again tried to create a new partition table and ended up with the same error
I then tried the KDE version, doing a custom partition layout I created my normal layout /boot, swap and / there was no problems with the installation
I then tried Gnome again but this time when doing a custom partition layout I did not create the partitions (because they had been created when I installed kde) but I did format the partitions as /boot, swap and / this time the Gnome version installed with no problems
Looks like there is a bug, as a work around create your partitions using a different live cd/dvd or just use fdisk

When doing a custom partition layout you need to have a minimum of / and swap, when you create these 2 partitions then the boot directory is created in the root. So the error that you hadn't selected the boot drive is because you did not select a partition to be your / or /boot
If you select a partition to be /boot then you still need to select another partition as /

If you use the text install there is no custom partition layout and the drive you select will be created as LVM

Some mistakes are too much fun to only make once!
