I had similar issues.


The following article pointed me in a better direction:

I tried to go the partition route, but for some reason the operation failed.


I decided to attempt a Lion install again afterwards anyway, but once again it failed, but now my whole system was hosed and could not revert back to Snow Leopard.


I did a restore from time machine. Once that completed, I attempted to install Lion again, and ta da! it works now.


What a pain.
