Before using the dustscat model in isis, did you explicitly
load the xspec module via require("xspec") ?

I ask because isis autoloads the xspec module only for models
that appear in xspec itself.  autoload doesn't work for local
models so they will only get defined when the xspec module is
explicitly loaded with LMODDIR appropriately defined.

If you run isis with the '-v' option, then load the xspec module,
you should see what files are being loaded.  For example, try:

 % setenv LMODDIR /usr/local/xspec_lmodels/i686
 % isis -v
 ...
 isis> require ("xspec");
 
This should show the path to the local model library as it
is loaded.

Does that help?

Thanks,
