Yes, off course (typo, as usual).

Camlimages was made by upstream, in order to have a fully modular design (
using plugin to register new formats). So, every parts are separated in
a library... I think, i maybe should enhance META.camlimages to be able
to choose only some modules...

which is not good...). Use the META provided in the other bug or wait for an
