1644	Problem with interface file (.hi) for a particular function	daniel.j.larsson@…		"I'm getting the following error:

    Can't find interface-file declaration for mkNSElement
      Probable cause: bug in .hi-boot file, or inconsistent .hi file
      Use -ddump-if-trace to get an idea of which file caused the error

When trying to call the following function:

{{{
import Text.XML.HXT.Arrow


mkNSElement :: Num a => QName -> IOStateArrow [(String, a)] b XmlTree
            -> IOStateArrow [(String, a)] b XmlTree
mkNSElement qn cs = proc x -> do
                      nss <- getUserState -< x
                      let ns = namespaceUri qn
                          (pfx, s) = case lookup ns nss of
