Hello Albert,
Thanks for taking the time to help me fix this package stuff. So I wiped out
my package.conf.d/ and tried to reinstall my stuff. Installing
template-haskell 2.5.0.0 is ok (2.6 is not, fails to compile on ghc 7.0.3)
but then:
D:\projets\>ghc --make -package ghc main
<command line>: cannot satisfy -package ghc
(use -v for more information)
I suspect I really *do* have to reinstall haskell-platform. Here is the
output of ghc-pkg list -v:

You have too many instances of template-haskell. The important parts are:
package ghc-7.0.3-**fc75cf67c86ba2c0d64b07024a18d3**b4 is unusable due to missing or recursive dependencies: template-haskell-2.5.0.0-**7d9b1443ac5ab69e5ed705a487990d**eb
package template-haskell-2.5.0.0-**7d9b1443ac5ab69e5ed705a487990d**eb is shadowed by package template-haskell-2.5.0.0-** 87f4f416a22a910e480ac9f269479a**5f
and in "ghc-pkg list -v":
D:/Program Files/Haskell Platform/2011.2.0.1\lib\**package.conf.d:
template-haskell-2.5.0.0 (template-haskell-2.5.0.0-** 7d9b1443ac5ab69e5ed705a487990d**eb)
C:\Documents and Settings\abailly\Application Data\ghc\i386-mingw32-7.0.3\ **package.conf.d:
template-haskell-2.5.0.0 (template-haskell-2.5.0.0-** 87f4f416a22a910e480ac9f269479a**5f)
I don't know how you got to this unsafe state. But my article explains what's wrong with it. (Though my example has different version numbers on top of different ABI hashes).
The user instance of template-haskell (**87f4f416a22a910e480ac9f269479a**5f) is getting into the way. Lose it by doing "ghc-pkg unregister --user template-haskell" on it. Oh, it will complain about breaking other packages; well, lose them too.
(Or go one step further and lose all of C:\Documents and Settings\abailly\Application Data\ghc\i386-mingw32-7.0.3\**package.conf.d which means losing all user packages.)
(Reinstalling haskell platform changes nothing, as long as some user package gets into the way.)
