The way that I always approach this is to create all CGI scripts that need to be called from SSI as modules which export a function which produces the necessary HTML output. I then create a wrapper script which just loads the module, prints a CGI header and calls the function. I can then call this script in an SSI call. When I need to use the same functionality within a dynamically created page I can use the module and call the function.
