Did you compile the 0.7.4 tarball, or the SVN version (which is .8)?  .8
uses an entirely different URL structure to pass options to the plotter, I
believe detailed in rtgplot.c.  

Also, check the error log for the webserver, to see if it's a configuration
issue (such as bad permissions, or no ExecCGI) or an actual problem with the
CGI itself.
