Comment (by sukhmel):

 [comment:2 mpickering], here are the steps:

 1. `wget
 http://downloads.haskell.org/~ghc/8.0.2/ghc-8.0.2-x86_64-deb8-linux.tar.xz`
 2. `tar -xJf ghc-8.0.2-x86_64-deb8-linux.tar.xz`
 3. `cd ghc-8.0.2`
 4. `./configure --prefix=/tmp/ghc`
 5. `make install`
 6. `time /tmp/ghc/bin/ghc -e 'putStrLn ""'`
