I was going by the contents of README.txt in the unpacked source bundle... it doesn't mention build via "ant" at all. Again, I'm a newb at java-based apps (but I won't be for long).

I did the build with "ant" (using some tips from
http://tinyurl.com/y9h9ho4 ) and things are running well now:

Note to any of you
that may be try Cassandra on Solaris for the first time: "ant"
is likely already installed, but by default isn't in your path. Add
"/usr/sfw/bin" to your PATH environmental to find

Thanks Jonathan!
