@Onyarian:
gphoto2 requires libtool, specifically libltdl. This is provided by autotools in 1.x, but I've not tested gphoto2 (or any other extensions that I've submitted) in 2.x yet. I will do that soon.
It should be sufficient to load libtool.tczl, which is available in 2.x. I will update the .dep asap. I am also preparing to submit version 2.4.5, which is newer than the currently posted 2.4.4.
@Juanito:
It would be nice to have libtool extension for 1.x to avoid the autotools dependency.
