[Haskell-cafe] installing haskell platform on 64-bit ubuntu 10.04 (Lucid)

Has anyone had problems getting Haskell Platform installed on Ubuntu 10.04? I've got GHC 6.12.1 installed via apt-get, and I've downloaded/untarred haskell-platform-2010.1.0.0.tar.gz. But when I run ./configure, it fails fairly quickly, with an error 'cause it can't build the "hello world" test program, complaining: <command line>: unknown package: haskell98 Anyone else seen this? Am I missing something obvious? --Andy
