If the other file is not in the same directory, you have to tell GHC where to look for it,

ghc -ipath/to/SimpleJSONDir:path/to/OtherImport --make UseSimpleJSON

or build a package with SimpleJSON in it (using Cabal) and register that, then ghc --make 
will know where to find it.

If the file is in the same directory, it may be an encoding error (or some case-muck-up), 
but definitely something bad.
