net-p2p/eiskaltdcpp supports Qt5 and the moc compiler from Qt 4.8.7 has problems with boost 1.58.0. Reproducible: Always
Created attachment 408202 [details, diff] eiskaltdcpp-9999.ebuild patch Proposed patch
Note: there is currently a discussion on qt4/qt5 USE on the gentoo-dev mailing list which this patch would then apply to this package.
Any news here? Eugene, I'd suggest to drop qt4 entirely in favor of qt5 to not further grow the massive REQUIRED_USE cluster. Considering Qt4 is going anway anyway.
Switched to qt5 in git commit 1238c6c6739a78c9a6be226e02f62a63209bc9ff.
