Hi, I had a strange behaviour with dev-qt/qtxml-5.6.1:5/5.6, dev-qt/qtsvg-5.6.1:5/5.6, dev-qt/qtprintsupport-5.6.1:5/5.6 and dev-python/PyQt5-5.5.1. emerge wanted to install them at each system update: airmure ~ # emerge -va --update --newuse --deep --with-bdeps=y @world These are the packages that would be merged, in order: Calculating dependencies... done!

Re-assigning to correct maintainer.
You needed to enable the compat USE flag on PyQt4.
The PyQt4 stuff is explained by the fact that emerge prefers to skip a package update (updating PyQt4 to 4.11.4-r1 in this case) rather than requesting/suggesting a USE flag change on a package that is already installed. That's undesirable in this specific scenario, but might make sense in others. In any case that's the current portage depsolver behavior and it's unlikely to change in the near future (or ever). The install/depclean cycle of PyQt5 is much more fishy though... and it must be caused by some other package, since pyqwt doesn't depend on PyQt5. Do you have any packages installed that depend on || ( PyQt4 PyQt5 ), e.g. qtconsole?
