Just some quick notes from my limited experiences in working on the tinydnsbackend:
- unless you 'make install', you will have to do something like --load-modules=./modules/tinydnsbackend/.libs/libtinydnsbackend.so in addition to the --launch
- i believe https://github.com/Habbie/powerdns/commit/264fa3874048f57e7296f981571216c25b2af174 contains all the changes i had to make to get the backend to compile and load

I hope this helps; do not hesitate to ask more questions!

Kind regards,
Peter van Dijk
