Hi, Thanks for reporting it, and sorry for the long delay.
Indeed, PyMapperGUI should depend on python-libmapper, which is already packaged for Debian. However, python-libmapper is not considered stable enought by the upstream to be in Debian testing/stable. See details here: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=768901 So I've just fixed PyMapperGUI package to depend on python-libmapper, but it will be only in unstable for now. I'll ping the libmapper upstream and check if they're going to release a stable release of their library soon. Bests, -- tiago
