Why is adding a new Ubuntu PC to an existing LAN such a pain?

It's kind of tangential to the actual problem, but can't you install a
DHCP server on one of the machines?

I was asking because older Ubuntu versions were blocking on boot,
waiting to receive an IP via DHCP if they were configured for DHCP.
Current Ubuntu versions however don't do this usually. I wonder why they
do in your case.

Anyway, if you don't have DHCP just set them to static. Go to menu
System/Administration/Networking. Select "Wired Connection", click
Properties, and set the Configuration menu to "static". Then enter the
network data (make sure all IPs are used only once on the entire
network)
