BashBurn 1.8.0 has been out for a while now (8th May) without anyone requesting a bump (that I can find anyway). I think all that is required is to rename the ebuild so I won't attach an updated one - obviously someone more experienced will want to try this out too but the program seems to be installed fine and is working.
Bumped in portage, thanks for info.
Exacly :) I did as you described some time ago and burned one dvd :) Quite cool app :)
