Quando tento incluir

<%= stylesheet_link_tag    "application" %>
<%= javascript_include_tag "application" %>

O conteúdo dos arquivos do aplicativo.css é:

/*
* This is a manifest file that'll be compiled into application.css, which will include all the files
* listed below.
*
* Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
* or vendor/assets/stylesheets of plugins, if any, can be referenced here using a relative path.
*
* You're free to add application-wide styles to this file and they'll appear at the top of the
* compiled file, but it's generally better to create a new file per style scope.
*
*= require_self
*= require social_stream
*= require_tree .
*/

E o conteúdo do arquivo application.js é

// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts,
// or vendor/assets/javascripts of plugins, if any, can be referenced here using a relative path.
//
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// the compiled file.
//
// WARNING: THE FIRST BLANK LINE MARKS THE END OF WHAT'S TO BE PROCESSED, ANY BLANK LINE SHOULD
// GO AFTER THE REQUIRES BELOW.
//
//= require jquery
//= require jquery_ujs
//= require social_stream-base
//= require social_stream-documents
//= require social_stream-events
//= require social_stream-linkser
//= require social_stream-presence
//= require social_stream-oauth2_server
//= require_tree .

my rails app não está incluindo os arquivos css e js que são necessários no snippet acima. mas quando eu atualizo as tags de inclusão para o arquivo específico, essas são incluídas bem. isto é

<%= stylesheet_link_tag    "social_stream" %>
<%= javascript_include_tag "jquery" %>

O que eu acho que há questão de rodas dentadas não está funcionando como esperado por favor conselho.

Eu serei muito grato a você.
