I was trying to install pandoc with the command `cabal install pandoc`, but 
then got the following error message. What's wrong?
```
[1 of 1] Compiling Data.Ipynb       ( src/Data/Ipynb.hs, 
dist/build/Data/Ipynb.o )

src/Data/Ipynb.hs:152:23: error:
    • No instance for (Ord Value)
        arising from the 'deriving' clause of a data type declaration
      Possible fix:
        use a standalone 'deriving instance' declaration,
          so you can specify the instance context yourself
    • When deriving the instance for (Ord JSONMeta)
