Due to events that have occurred upstream, I have decided to stop maintaining app-shells/ksh for Gentoo.
If you are interested in maintaining this package, I suggest reading through this issue. https://github.com/att/ast/issues/1466 To summarize, due to some vocal members of the KSH community, a developer at AT&T decided to roll back all changes that have been made in the last decade, and point the master branch at the last official AT&T release (ksh93u+). The developers who were updating the code for the last few years seem to have given up and have not made any contributions to any fork since February 2020. Feel free to ping me if you want to pick this package up and need help getting started.
