Khal’s releases (0.11.2 as packaged in Gentoo, and 0.11.3 which is out but not packaged) work with major version 5 of the icalendar package. They don’t work with version. There is an open effort to migrate linked which I’ve linked in the URL field, but it’s not done yet; the linked URL describes things that don’t work with icalendar 6. Therefore the Gentoo package should have a versioned dependency.
