Missing build-dep network-uri

[FPtje]

MediaWiki/Util/Fetch.hs:28:8:
    Could not find module ‘Network.URI’
    It is a member of the hidden package ‘network-uri-2.6.0.1’.
    Perhaps you need to add ‘network-uri’ to the build-depends in your .cabal file.
    Use -v to see a list of the files searched for.

ghc version: ghc-7.8.3-2
Cabal version: 1.20.0.3-2
OS: Linux
network-uri should be added to build-deps

When that's done I get these errors:

MediaWiki/API.hs:58:40:
    Couldn't match type ‘text-1.1.1.3:Data.Text.Internal.Text’
                  with ‘[Char]’
    Expected type: String
      Actual type: text-1.1.1.3:Data.Text.Internal.Text
    In the expression: showMIMEType form_mime_ty
    In the expression: ("Content-Type", showMIMEType form_mime_ty)

MediaWiki/API.hs:64:30:
    Couldn't match type ‘[Char]’
                  with ‘text-1.1.1.3:Data.Text.Internal.Text’
    Expected type: SubType
      Actual type: [Char]
    In the first argument of ‘Application’, namely
      ‘"x-www-form-urlencoded"’
    In the expression: Application "x-www-form-urlencoded"
    In an equation for ‘form_mime_ty’:
        form_mime_ty = Application "x-www-form-urlencoded"

I got these on both Windows and Linux.
