can't build dahdi-source (error: 'struct net_device' has no member named ...)

I want to dive into asterisk.. at least for experimenting a little but with it.

After having some installation issues (the apt-get install process breaking because there was no dahdi kernel module) I uninstalled asterisk and installed dahdi-source so that I could build it before i installed asterisk (shouldn't that be handled with a requirement to asterisk?... anyway).

After I installed dahdi-source, I tried to make it, and see what happened:
