Hi all, Rasmol upstream is not dead, it's just resting :)
The current sources live at https://github.com/rasmol/rasmol/tree/rasmol-2.7.6 and contain a gtk3 port which I made in the spring. Unfortunately I got distracted by other projects before I could finish the Debian packaging. There are also library dependencies which I would like to upgrade before rasmol itself. I see that there has been some (possibly duplicate) effort here to get this bug fixed and I'm sorry that I did not communicate about the development that has been made elsewhere. I will integrate the new upstream code to the salsa repo soon. Best, Teemu
