[Haskell-cafe] Cannot install the Haskell Platform on GNU/Linux (possible Cabal issue)

[egarrulo]

Hello guys,

I cannot install the Haskell Platform 2014.2.0.0 on my GNU/Linux system:

     $ ./platform.sh \
     >      --prefix=/opt/haskell-platform/haskell-platform-2014.2.0.0 \
     >      ../ghc-7.8.3/ghc-7.8.3-i386-unknown-linux.tar.bz2
     Warning: The following packages are likely to be broken by the
     reinstalls:
     haskell-platform-2013.2.0.0
     Use --force-reinstalls if you want to install anyway.
     === pre-requisite packages for hptool are not installed
         run the following:
         cd hptool ; cabal install --only-dependencies

However, the dependencies for *hptool* are already installed:

     $ cd hptool ; cabal install --only-dependencies
     Resolving dependencies...
     All the requested packages are already installed:
     Use --reinstall if you want to reinstall anyway.

The existing Haskell system:
  - GHC 7.6.3
  - Haskell Platform 2013.2.0.0
  - cabal-install 1.16.0.2 (using Cabal library  1.16.0)

Any help?  Thank you.
