ALMiniumにRedmine Charts 2をインストールする方法

ALMiniumでチャートが表示されなかったのでCharts 2をインストールしました。
Redmine 2.0からはCharts 2でチャートを表示できます。

GitHub - pharmazone/redmine_charts2: Plugin which integrates with Redmine 2.0.3 and 2.1.x following charts: burndown, timeline, ratios of logged hours and issues, deviations of logged hours.

Charts2のインストール

# cd /opt/alminium

# git clone git://github.com/pharmazone/redmine_charts2 plugins/redmine_charts2

# cd plugins/redmine_charts2

# git checkout redmine21

# cd /opt/alminium

# rake redmine:plugins RAILS_ENV=production

open_flash_chartを更新

「plugins/open_flash_chart」を削除してインストールし直しました。

# rm -rf plugins/open_flash_chart

# git clone git://github.com/pullmonkey/open_flash_chart.git plugins/open_flash_chart

# cp -r plugins/open_flash_chart/assets public/plugin_assets/open_flash_chart

古いChartsを削除

Apacheを再起動したときに下記のエラーが表示されるようになってしまいました。
エラー内容からCharts2のメニューが追加できないことが分かり、古いChartsプラグインを削除したところ解決しました。
