[OSM-Photos] Encouraging contribution: Installation problem

[H.S.Rai]

I found that things are a lot difficult for new contributors (of
course, including me ;-) ). The requirements needed to be mentioned
along with version, if version matter.

After a lot of time, doing experiments, I can summarise procedure to
have a local copy (Correct if something is wrong).

Steps to install OSV on your computer (Mine is with Ubuntu 10.10).
=================

sudo apt-get update
sudo apt-get install rake gem ruby1.8-dev
sudo gem install rails -v 2.3.8
git clone git://github.com/johnmckerrell/OpenStreetView.git

// or

git clone https://github.com/johnmckerrell/OpenStreetView.git
cd OpenStreetView
joe config/database.yml

// Change user and password of MySQL

joe config/environment.rb

// Change server name from www.openstreetview.org to localhost in line
// number 7, in line number 4, make version for RAILS_GEM_VERSION as '2.3.8'

rake
sudo rake gems:install
rake
=================

Above give error for OSV, but make RoR works fine and give environment as:

Ruby version	1.8.7 (i686-linux)
RubyGems version	1.3.7
Rack version	1.1
Rails version	2.3.8
Active Record version	2.3.8
Active Resource version	2.3.8
Action Mailer version	2.3.8
Active Support version	2.3.8
Application root	/home/meet/OSV/Rai/RailTest
Environment	development
Database adapter	sqlite3
Database schema version	0
===================

But when trying on OpenStreetView, it through error as given below signature.

Please help to make it running. What is wring in installation.
