You mean: "ksh93 -I depfile myscript" ? It is the preferable solution.
I hope you at least investigate it. (Ksh93 is freely downloadable
through
kornshell.com).

It would be a pity if you couldn't use it, because the AT&T AST
library
(including ksh, cdb, ciao, ...) is a 1000 man-years of software tools
primarily devised for reverse engineering of complex legacy software.

This is a practical goal. If the above doesn't pan out,
GraphViz (or even better, WebDot) is a free and viable solution,
although you will have to generate the dependency table yourself.
Here is an example (with source, so cheat!):

GraphViz/WebDot example: "Module Dependencies":

http://www.graphviz.org/webdot/

"WebDot.tcl": GraphVix GUI
http://www.graphviz.org/webdot/demo.html # look at "jsort"

I was thinking that "scriptran" just might be a java executable,
and therefore runnable on non-Solaris systems (if' that what
you have -- you didn't mention); it is at least worth investigating:

"scriptran": "Bourne shell script analysis tool"
