And it hasn't been fixed in ubuntu either:
http://people.canonical.com/~cjwatson/cross/armhf/raring/ppp_2.4.5-5.1ubuntu2_armhf-20130206-1041
BUt all the cross-build-deps are available, at least in Ubuntu raring,
probably not in debian yet.
This patch makes it build (but cheats by turing off the udeb build
which broke for me due to a missing
'pppd-udeb/plugins/rp-pppoe/pppoe-discovery')
I assume that's fine from your POV.
