Hello Joe:
My guess is that AFNI_MODELPATH or ANFI_PLUGINPATH or PATH includes a directory
containing old binary files, such as model_*.so, which were compiled under a
previous version of AFNI, and are not compatible with the current AFNI.
If so, then you can either modify the path variable to exclude the obsolete
directory, or remove the individual obsolete "model_*.so" files.
