You're right. That's apparently a bug in Ubuntu and/or in Debian. When I
build libtheora from the sources, the theoradec.pc and theoraenc.pc
files are generated.

I will report this. Thank you very much for your help and for your patience!

By the way, here's a minor patch for oggSilence:

Without it, you get the impression that oggSilence won't get built.

Thanks again for everything,
