redmine2.0.2 install problem

redmine2.0.2インストール時に環境不足でエラーが発生。
下記のように事前に環境を用意しておくのと、postgresqlとかsqlite
などを使わないのであればbundle install時に指定する。

bundle install --without development test
below message

yum install ImageMagick-devel
yum install ruby-devel  % ( for /usr/lib/ruby/ruby.h undefined )
yum install mysql-devel
gem install mysql

if DATABASE Server Soft is mysql that sqlite and postgresql is not need to install.

bundle install --without development test postgresql sqlite
