I just wanted to add the comment "works here" for @0.9.20pre10.  This is probably more helpful to Frank than Ellen, but it would seem that it something unique to Ellen's configuration.  I am running Mavericks 10.9.5 by the way.

I could not find information about this problem in the Mail Archive, though I may have missed something. Do I need to download the PDL perl modules separately from the Demeter installation? Could there be files that are not located in the proper directory? Or perhaps PCA is simply not available for Macs?
