[Haskell-beginners] HXT runtime error

[aditya siram]

Hi all,
I am trying to use HXT to parse an XML file. However whenever I try and run
'xread', GHCI crashes. The code and output are below.

The following code queries isbndb.com ( a book ISBN database ) which
responds with XML describing the book. I am using 'xread' from HXT to parse
the response into an XMLTree.

respHTML'' isbn = do
      rsp <- simpleHTTP (getRequest $ "
http://isbndb.com/api/books.xml?results=details&access_key="
                                ++ key
                                ++ "&index1=isbn&value1="
                                ++ isbn :: Request_String)
      case rsp of
        Left x  -> putStrLn $ "Error " ++ (show x)
        Right r -> putStrLn $ show $ xread $ rspBody r

When I try this respHTML'' in GHCI usin the isbn for "Real World Haskell" ,
this is what I get:

GHCi runtime linker: fatal error: I found a duplicate definition for symbol
   my_inet_ntoa
whilst processing object file
   /home/deech/.cabal/lib/network-2.2.1.2/ghc-6.10.3/HSnetwork-2.2.1.2.o
This could be caused by:
   * Loading two different object files which export the same symbol
   * Specifying the same object file twice on the GHCi command line
   * An incorrect `package.conf' entry, causing some object to be
     loaded twice.
GHCi cannot safely continue in this situation.  Exiting now.  Sorry.

It seems to want to load the 'network' package twice. Is this causing the
trouble?

thanks ,
deech
