[Haskell-cafe] apt-get install haskell-platform fails on ubuntu 14.04

http://askubuntu.com/questions/597278/haskell-platform-unmet-dependencies I'm installing on a newly-built system. I looked at the haskell.org download instructions, and I couldn't find anything that made sense. apt-get install haskell-platform worked about a month ago. Does anyone know what happened?
