dev-python/PyQt4 masked for removal on Gentoo

[marcodifresco]

Hi,
first I want to thank you for PyLotro.

I want to report that on Gentoo dev-python/PyQt4 has been masked and it will be soon uninstalled: https://packages.gentoo.org/packages/dev-python/PyQt4

Not remembering it was required by PyLotro I preemptively removed myself and now I get the following error message:
Traceback (most recent call last): File "/usr/bin/pylotro", line 31, in <module> import PyLotROLauncher.Runner File "/usr/lib64/python3.5/site-packages/PyLotROLauncher/Runner.py", line 30, in <module> from .MainWindow import MainWindow File "/usr/lib64/python3.5/site-packages/PyLotROLauncher/MainWindow.py", line 34, in <module> from PyQt4 import QtCore, QtGui, uic ImportError: No module named 'PyQt4'

For the short term I can override Portage (Gentoo's package manager) and re-install dev-python/PyQt4, but considering that over time other distros will drop PyQt4 too, it may be useful to start porting to PyQt5.

Thanks and best regards.
