You need to add "-1" or "--oneshot". As this has been used, I would definitely expect the world-file to be full of this, causing issues with updates later. Also, by restricting to @system, any packages not in @system with a restriction on readline V8 will cause the mentioned problem. @system is, for me, a lasr resort, but I tend to move my world file away (rename) and put it back once @system is done and a depclean finished. This is usually only needed after not updating for a while and/or big changes in the tree. -- Joost -- Sent from my Android device with K-9 Mail. Please excuse my brevity.
