I've built the slackware packages of rails.

rails path is: /frm/ruby/1.8.6/lib/ruby/site_ruby/1.8

RUBYLIB : /frm/ruby/1.8.6/lib/ruby/site_ruby/1.8:/frm/ruby/1.8.6/lib/
ruby/site_ruby/1.8/i686-linux/

I could created the rails application, but files are missing.

Config
    - boot.rb, database.yml, environment.rb and routes.rb
Public
    - 404.html,500.html,dispatch.fcgi,favicon.ico,index.html,422.html,
dispatch.cgi
          and dispatch.rb

Script
    - about, console, dbconsole, destroy, generate, plugin,
runner,server
Test
    -test_helper.rb

I am getting below error on while creating the app.

No such file or directory - /usr/bin/../lib/rails_generator/generators/
applications/app/../../../../../fresh_rakefile

Please help

How did you install rails? I suggest you build gem from source using
your customized install of ruby and then do

gem install rails

Also, is there any reason why you are not using the ruby which came
standard with Slackware?
