[Haskell-beginners] cabal install local troubles (osx)

[luc taesch]

On Osx 10.8, I recently run into 32/64 issues.
so I was advised to reinstall HP 2012.4 64, which I did.
to be sure, I wiped ( moved) my ./~cabal

after resintallation I was suprised to find it nearly empty, and all 
files are now into ~/Library/Haskell
( and the Path is to be updated accrodingly,as mentionned in the install)

note this only occur when your ~/.cabal is non existing at installation time
as documented below


http://www.haskell.org/haskellwiki/Mac_OS_X_Common_Installation_Paths


Haskell Platform 2011.2.0.0 (March 2011) and later uses this layout and 
sets up cabal to use it for built packages. On new installs, if you 
didn't already have a ~/.cabal/config file, then it is set up by 
default. Otherwise, the config file for this layout is placed in 
~/.cabal/config.platform and you can manually move it over, or 
incorporate it into your existing config file.
