One more thing ... the INSTALL document says for step 10 that its for 
"Solaris Only and Optional".

In many ways, this is true but for a first time user its also very 
confusing.  On a Solaris system, you need to install the SE toolkit when 
gathering system perf stats to get the graphs you see on the Orca example 
page - so on a Solaris system its kinda NOT optional.

Orca is actually two pieces:

- A data collector
- A grapher

The data collector can technically be anything as long as the resultant 
data is recorded in a specific layout.  For Solaris system perf statistics, 
this is the SE Tool kit and the orcallator.se script.

The grapher reads in the data stored by orcallator.se (or any other data 
collector) and processes it into RRD DB files.  Then graphs are generated 
from the RRD files.  This is Perl (with several Perl modules) and 

This is kinda what step 10 is referring to.  On a Solaris system, you can 
install Orca and use your own data collector without the using SE Tool 
Kit/orcallator.se if you want.  Of course, you will have to create your own 
data collector from scratch.
