For the life of me I can't figure out how to install pandoc. I tried the approach recommended on its Github repo as well as all 3 approaches recommended on the pandoc site. I'm installing on Ubuntu 12.04 so I first did sudo apt-get install haskell-platform.

Here's where the error occurred at each step:

1) Installing as recommended on the Github repo:

# cabal install --enable-tests

Registering zlib-conduit-1.0.0...

cabal: Error: some packages failed to install:

http-conduit-1.9.4.5 depends on mime-types-0.1.0.3 which failed to install.

mime-types-0.1.0.3 failed during the building phase. The exception was:

ExitFailure 9

pandoc-1.12 depends on mime-types-0.1.0.3 which failed to install.

2) Primary installation method on Pandoc site:

# cabal install pandoc
