pstack has been around since the SunOS days, long before dtrace was in
Solaris, so it at least used to operate some other way. I know they added
some features to Solaris 10 that let pstack look into Java librarites that
may leverage dtrace, but I don't believe the internals of the main pstack
tool rely on it when looking at regular processes.
It's also worth noting that there's a similar Linux utility called gstack.
