I understand...

Everything looks all right:

Here are the contents of /usr/lib/pkgconfig/theora.pc:

# theora installed pkg-config file


Name: theora
Description: Theora video codec
Version: 1.0final
Requires: ogg >= 1.1
Libs: -L${libdir} -ltheora
Cflags: -I${includedir}

There could be something missing in Ubuntu 9.04 too...

That's very nice of you, thank you very much!!!

As soon as this is fixed, I'll be able to release the script I'm working
on... Basically, this scripts takes an Ogg/Theora video and a png image
as input, and generates a new video with an intro based on this image.
