You forgot a directory level, and you hardcoded Windows style slash. 
This works for me:

| slash |
slash _ FileDirectory slash.
{
 'packages', slash, 'PetitParser', slash, 'PetitParser.pck' .
 'packages', slash, 'PetitParser', slash, 'PetitTests.pck' .
 'packages', slash, 'PetitParser', slash, 'PetitTutorial.pck'
}
 do:
    [ :fileName | CodeFileBrowser installPackage:
                      (FileStream concreteStream readOnlyFileNamed: 
fileName)
    ]

BTW, always keep a Transcript open. You get notifications about 
installed packages, in addition to the usual undeclared, etc.

Cheers,
