[pca] PCA features: Check if SST(aka JASS) is installed on the system to analyze.

Hi Michele,

It's probably fine to do such things in a wrapper, like other local 
checks, or advices from the senior to the junior administrators.

The fact that SUNWjass is installed doesn't have to mean that it is 
used, and the more informational output a tool creates the less it is 
read, I guess. It's probably common sense to run any hardening tools 
again after a system modification (like a patch install). I don't think 
that a patch should modify a system in a way that makes it more unsecure 
than it was before by changing some settings, and I can't remember any 
such issue ..

Thanks for the feedback, anyway.

Martin.
