Hsc2Hs/hGetContents encodings error (was: ANNOUNCE: GHC 6.12.1 Release Candidate 2)

[Daniel Schüssler]

Hi,

I don't think this is the same problem as the one mentioned by Alex 
(installing `network' works for me):

{----------------------------------------------
$ cabal install X11

X11-1.4.6.1 failed during the building phase. The exception was:
ExitFailure 1
----------------------------------------------}


Converting the offending file (Extras.hsc) to UTF-8 manually solves it:


{----------------------------------------------

$ file Extras.hsc                                                     
Extras.hsc: ISO-8859 English text                                       

$ <Extras.hsc iconv -f ISO-8859-1 -t UTF8 >temp                                       
$ mv temp Extras.hsc 
$ cd ../../..                                                                           
$ cabal install                                                                        
[OK]

----------------------------------------------}



Greetings,
Daniel
