Long story short: 1. install old poppler and inkscape, 2. upgrade poppler. inkscape has a := dep on poppler, so it's going to be rebuilt after the upgrade. However, it fails to build with new poppler, so you end up with inconsistent dependency tree and preserved libpoppler. Sadly, this also means that 'emerge --depclean' isn't be able to proceed since inkscape depends on no-longer installed version of poppler. Not sure if there's a valid solution for this.
Just a data point from a mixed stable amd64 installation: media-gfx/inkscape-0.48.4-r1 got rebuilt without problems here after upgrade to app-text/poppler.0.24.5 a week ago (from 0.24.3), and media-gfx/inkscape-0.48.4 would seem to compile OK as well.

I guess the only solution to this is to mask the new poppler when you notice a rebuild failed. A subsequent -uDN world should also try to rebuild inkscape again. > > Sadly, this also means that 'emerge --depclean' isn't be able to proceed > since inkscape depends on no-longer installed version of poppler. > There's not much one can do, it's just to risky to trust --depclean when there are unsatisfied dependencies. Just assume inkscape is the last package that depends on poppler and you ignore the missing dependency. Then poppler will end up with no reverse dependencies and be cleaned together with its otherwise unused deps. > Not sure if there's a valid solution for this.

Yes, it does. And then tries again. And again... Curious enough, after I unmerged inkscape and installed it again, it built fine. I smell something funky. > > Sadly, this also means that 'emerge --depclean' isn't be able to proceed > > since inkscape depends on no-longer installed version of poppler. > > > There's not much one can do, it's just to risky to trust --depclean when > there are unsatisfied dependencies.
