on Linux installations of CASA indicate that the "geodetic" directory of your CASA installation needs to be updated.

Instructions for performing this update are in the Knowledgebase article How can I update the data repository copy of my CASA installation? It is advisable to install a cron job which performs the update regularly.

With the OSX distribution of CASA, the update should be done automatically at each startup.
