Removed /root/.cabal by mistake - how to solve this issue?

I have mistakenly removed /root/.cabal/ from my root directoty and when I tried to reinstall it I get this output:

Code:

faiz:~$ sudo cabal install pandoc --reinstall
Resolving dependencies...
In order, the following will be installed:
pandoc-1.14.0.4 (reinstall)

cabal: Error: some packages failed to install:
pandoc-1.14.0.4 failed during the building phase. The exception was:
ExitFailure 1

The problem, I believe has to deal with Haskell installation. I have no experience with Haskell, and I only need a package called "pandoc" for some work with R. What should I do to reinstall pandoc again? I also want to know what's the difference in installing pandoc (using cabal) from the root command line (#) and installing it using the sudo command? (sudo cabal install pandoc.) I use a netbook that has crunchbang linux (basically Debian Wheezy)
