Did you use Synaptic Package Manager in your administration folder in your Elyssa / Daryna / Cassandra /......Menu? I pulled up Synaptic (it's a pretty nice gui if you want to stay clear of terms) did a search for lmms, clicked lmms, it selected all the dependancies and seems to work fine......Word of warning about Synaptic however. You have access to Ubuntu repos in this and if you start trying to download everything, (in my instance, KDE Desktop!) You will have a mess. If you know what programs you want though, you should be fine. I did notice just now that after it installed it didn't add to my Elyssa menu. I had to go to the term and type lmms, hit enter, then follow the gui's. Have fun.
