fwalch  filed a request to merge libvterm-bzr  into pangoterm-libvterm-bzr :
This package provides the same library as "pangoterm-libvterm-bzr".
It is unfortunately NOT the same libvterm as the one provided by "libvterm", which has not had a release since 2013. The "pangoterm-libvterm", OTOH, is actively developed and used by Neovim and Pangoterm, so maybe what's currently packaged as "libvterm" should be renamed. But I guess that's something for another request.
