I encountered the following errors:

!   dev-dotnet/microsoft-aspnet-mvc
    Reasons: dev-util/monodevelop-6.1_p2016062206:0::shnurise
    Unsuitable candidates:
      * Found no packages for resolvent dev-dotnet/microsoft-aspnet-mvc:(unknown)::(install_to_slash)

the build is temporarily broken - http://scrinfra.sabayonlinux.org/logs/2018-03-16/dotnet.1521159033.log
I will work on resolution, but it will take time (months)
before that time please see oiledmachine overlay - https://github.com/orsonteodoro/oiledmachine-overlay/tree/master/dev-util/monodevelop
I don't like the decision to use git-r3 because it requires online fetching, that's why I will do my own in the future.
