Hi, Antoine Latter and Daniel Fisher.  Thanks your direction.  My old URLs are:
1.www.haskell.org/ghc/dist/7.0.3/ghc-7.0.3-i386.tar.bz2 for the ghc package; and
2. hackage.haskell.org/platform/2010.2.0/haskell-platform-2010.2.0.0.tar.gz.

I'll try your instruction on my new portable when it is delivered in order not to screw up my current set up.  Is 2010.2.0 the current platform that support ghci 7.0.4?? Th.anks again.

Have a nice day.  Simon.

I would, however, recommend going for the new

http://www.haskell.org/ghc/download_ghc_7_0_4

which fixes a couple of bugs in 7.0.3
