[pca] List: missing

[McGranahan, Jamen]

After much trial and error, I've been able to get PCA to run correctly,
but every time it runs, we see this message:

List: missing

Looking at the perl scrip, I see this line:

print "List: @slist\n\n"

I'm assuming that is what this message is pulling from. Am I correct?
What is the @slist variable and how is it defined?

I do see this in the Variable declarations:
my (@plist, @slist, @rlist);

We're just trying to understand what this message means. Please advise.
Thank you!
