pdfsandwich says that it is a wrapper that uses "convert", however the current dependencies do not include any application that provides "convert". I attempted to override and use the "econvert" binary provided by the exact-image package that is listed as a dependency, however I received a number of errors about "econvert" not supporting the arguments passed to it. My recommendation is to add media-gfx/imagemagick as a runtime dependency. This should apply to all of the versions in portage. Reproducible: Always
media-gfx/imagemagic needs use flag png to deal with pbm and png files.
Thanks, this is fixed in -r1 together with an EAPI bump. I removed old ebuilds. + 07 Aug 2014; Thomas Kahle <tomka@gentoo.org> +pdfsandwich-0.1.2-r1.ebuild, + -pdfsandwich-0.0.7.ebuild, -pdfsandwich-0.0.8.ebuild: + EAPI bump, add missing dep on *magick (bug 519282), remove old
