gtk-vnc could offer more use flags. attached is an ebuild to enable/disable: a) the python bindings b) the examples (installes gvncviewer, maybe one could add a .desktop entry) c) the nsplugin Reproducible: Always Steps to Reproduce:
Created attachment 144992 [details] gtk-vnc-0.3.3.ebuild
The nsplugin is considered sample code, not for use, was my understanding from reading NEWS and changelogs. Which is why I didn't add that particular USE flag when I bumped to 0.3.3. I don't know about the rest, as I only paid attention to the changes between the versions.
partly fixed with the commited 0.3.4 version.
I'll leave nsplugin for later when upstream considers it less experimental. No desktop file for the test program because it's a test program and I don't really like test programs cluttering up menus. If somebody feels differently you're free to change the ebuild of course.
