Ok, thanks!

Thanks, this was precisely what I was missing :)

Seems that with my little CEDAR all fail... although the failure (or at
least part of the output) seems related to babl. I have to say, that I
built babl and I use its libs by adding -L/pathtobabllibs/ to BABL_LIBS
when configuring and to LD_LIBRARY_PATH when testing, maybe it's related
to this.
Here's the output for the first test:

Sure, same for you!
