Installing Developer CASA
Installing CASA from a users point of view is trivial. Install the correct binary tar ball, add the correct bin/ directory to your $PATH, and type casapy. At UMD we use astromake, so a command like astroload casa will probably do the job. However, the current user release does not (currently) enable you to develop application. For this a developer release must be installed, from source.
As of this writing (Feb 2009) the original CASA is being split into casacore and the non-code (code) trees.
