Since the webcal.cgi is called form a CGI script it thinks it is called as a CGI itself. If it takes the parameters from @ARGV if you execute it from the prompt you migh try to delete $ENV{QUERY_STRING} and $ENV{REQUEST_METHOD} before calling the webcal.cgi. Then it will most probably work.

Another thingie ... you've mentioned Selena Sol as the author of the webcal.cgi. I seem to remember some very bad reviews of her scripts. Actually anything that doesn't use CGI or CGI::Lite (or somesuch module), but contains a CGI parameter parsing code is suspicious.
