dailystrips needs be recompiled.
if you do pacman -Rs dailystrips pacman would not respond in a million time. I don't know why but it does [maybe it shouldn't happen cause dailystrips depends os libwwwperl for exmaple which became with Prodives and Replaces perl-libwww] But hey that's for Judd to find out :)

So it just needs a new revision [the project seems to be dead]. and since you the maintainer will provide that revision, you can include an updated strips.def, for some comics to work. it can be found here:
