This looks like you didn't run "make depend" at the right time(s). Any
time you change your config file (or anything the config file
controls), it's a good idea to run "make depend" unless you absolutely
know what you're doing.

It's even different on 1.1. I've used PPP on 1.1 for quite some time
without any ed* devices in my config.

Perhaps if you post your config file someone can help further.
