This might sound rude but since you are using Ubuntu all around why
don't you ask them for help?

You are using pbuilder to compile your source. That builds the source
ina clean chroot with just the build-essential packages and your
Build-Depends. I'm guessing you did not add any Build-Depends so stuff
will be missing during build.

Also pbuilder cleans up the chroot after build so your config.log gets
removed along with it.

Maybe you should start packaging something simpler than a library and a
bit more complex than hello as an exercise. Build up your skills slowly.
