$ gem install radiant
$ gem install will_paginate
$ gem install compass
 
$ radiant --mysql /home/USERNAME/YOURAPPIR
 
# ...just follow default install procedure and at the end...
 
$ cd YOURAPPDIR
 
$ rake gems:unpack
 
$ cd vendor/gems
$ gem unpack compass
 
# Edit config/environment.rb and change
# this line:
config.gem 'will_paginate', :version => '~> 2.3.11', :source => 'http://gemcutter.org'
 
 
# by this:

###  Sinatra on Dreamhost - 13/13/2010
 
### Installing Rubygems into another path while using Ruby from Dreamhost (without rvm for now)
 
$ mkdir ~/.gems
$ mkdir ~/bin
$ mkdir ~/lib
 
$ mkdir ~/src
$ cd ~/src
$ wget http://rubyforge.org/frs/download.php/70696/rubygems-1.3.7.tgz
$ tar xzvf rubygems-1.3.7.tgz
$ cd rubygems-1.3.0
$ ruby setup.rb --prefix=$HOME
 
 
### Changing ENV
 
# Add the next 3 lines in to ~/.bash_profile
 
export GEM_HOME="$HOME/.gem"
export GEM_PATH="$GEM_HOME"
export RUBYLIB="$HOME/lib:$RUBYLIB"
 
# also in your ~/.bash_profile change the line bellow
 
export PATH="$HOME/bin:$HOME/.gem/bin:$HOME/.gem/ruby/1.8/bin:$HOME/usr/local/bin:$HOME/usr/bin:$PATH"
 
# load the changed .bash_profile
 
$ source ~/.bash_profile
 
 
### Installing Sinatra and Tilt to ~/.gems
 
$ gem install sinatra -v 1.0
$ gem install tilt -v 1.0
 
$ cd YOURAPP
$ mkdir vendor
 
### unpack gems to your app vendor
 
$ gem unpack sinatra -v 1.0
