解決 Cacti 出現 RRDTool version does not match configured version 的訊息

在 Cacti 管理畫面 Console / System Utilities / Technical Support 畫面中，出現的警告訊息：
ERROR: Installed RRDTool version does not match configured version.
Please visit the Configuration Settings and select the correct RRDTool Utility Version.

檢查系統安裝的 RRD Tool 版本，是 1.5.5-4
# dpkg -l | grep rrd
ii  librrd4:amd64                      1.5.5-4                            amd64        time-series data storage and display system (runtime library)
ii  rrdtool                            1.5.5-4                            amd64        time-series data storage and display system (programs)

可是在 Console / Settings / General 頁面中，RRDTool Utility Version 只有 1.0~1.4 版可以選擇

[@more@]解決方式：
