Problem when compiling ghc-6.4 with itself

[Alain Cremieux]

When compiling ghc-6.4.20050211 with itself, I get :

/usr/local/bin/ghc -M -optdep-f -optdep.depend  -osuf o    -H16m -O 
-i../../lib/compat -Rghc-timing -Wall Main.hs
../../lib/compat/Compat/RawSystem.hs:19: ../../includes/ghcconfig.h: No 
such file or directory


I verified the version of ghc :

/usr/local/bin/ghc --version
The Glorious Glasgow Haskell Compilation System, version 6.4.20050211
