[gentoo-user] How to mask or remove new ebuild

[Raphael MD]

Hi,

KDE Appear to be a nightmare, because every 'emerge --sync' I do to solve
other problems, if KDE base has an updated version issued, and you,
acidentaly, need to install any other KDE packages that you don't have
installed yet, you suffer with a lot of dependency updates problems.

De fato, you need to update whole KDE base.

Now I need to install Kdevelop-5.1.0, and emerge are asking to install
kde's dependencies' version 5.7.1. My installed versions are 5.6.2. But
emerge even it I masked those packages, refuse to install.

How do I can proceed?

Thanks.
