32 FWIW, libpng-1.5 is soon to be stabilized, with remaining apps that don't
33 work with it masked for removal.
34
35 As it happens, there's a really long thread on gentoo-dev about it ATM,
36 since someone wasn't following mask-for-removal policy and at least one
37 package was removed before the 30-days-in-packagemask clock expired,
38 causing the package maintainer, who happened to be on vacation and thus
39 not catch it in time given the far shorter than normal masking, to
40 complain rather loudly about the policy violation.
41
42 But for what concerns this, I'd suggest keywording libpng-1.5.x for the
43 time being and doing the necessary rebuilds, as it's very close to being
44 stabilized anyway, and whatever remaining packages break with it are very
45 possibly going to be removed (if they haven't been already, AFAIK
46 everything they know about is either fixed or masked by now) in any case.

54 As I, at a rather great time and hassle cost, switched to kde4 when
55 upstream was dumping kde3 (despite promises to the contrary, but that's
56 history now), and kde4 switched from hal with 4.6, I have little current
57 info on either end of this.
58
59 However, from what I've read, this is one of the things the trinity folks
60 are-dealing/have-dealt with since hal is pretty clearly toast at this
61 point. Since I've not even touched kde-sunset overlay, I've no idea if
62 there's builds for their releases or not, but if so, I'd presume they'd
63 be 3.5.11+. So you may wish to try those (if available) and see what
64 happens. But hopefully someone with rather more reliable and kde-sunset
65 specific information replies with better guidance here than I'm able to
66 provide.
