So, here's[1] the package "directory", however it ships with GHC, so
you very probably already have it installed. Try `ghc-pkg describe
directory` to check. Also, run `ghc --version` to see what version of
GHC you are running. If it's < 6.8, you may have problems because the
directory package didn't exist before then, I believe the same modules
were in the base package. In that case, the easy solution is probably
to upgrade GHC.
