I went to look up libmodplug and I installed "libmodplug-dev" and I already have "libmodplug0c2" installed but can't see any "libmodplug1". I still get the same error so I'm kinda clueless as what to do next.
I had the same problem with the last version. What wound up working was just adding the PPA to my sources list and getting it through there. (I also wound up compiling it, but the insane list of development libraries to download seems like a bit much to any who don't want to modify LÖVE.)
sudo add-apt-repository ppa:bartbes/love-stable
sudo apt-get update
sudo apt-get install love
and it looks like it is all good to go Unfortunately the older version game I grabbed off the love wiki doesn't work lol. Got another game that was 0.7.0 and it works fine though.
I was using the 10.10 deb, at least that was my intention and the filename supports that claim. I used "love_0.7.0~10.10ppa1_i386.deb" downloaded from the home page.
Someone over at the ubuntu forums also said they have 10.10 and can see libmodplug1 in the main repository. So maybe something is funny with my system, I'm just too much of a newb still to know what.
