CGI scripts: What has changed between Apache A.3 and Apache 2.0?

Hi,

I have a few CGI scripts that worked fine under mandrake 8.1 and apache
1.3.?, but having UPGRADED (ie not a new installation) to Mandrake 9.1
and Apache 2.0, I keep on getting a 'file not found' error whwn I run
the scripts - in var/log/httpd/error22.log.

The CGI scripts appear to work fine when called via 'perl -d
scriptname', but fail when called via a Web page.

What has changed in Mandrake 9.1 vs 8.1? Is it Perl or Apache? and where?

I have also finally managed to some debug info...

the /var/log/httpd/error22_log file says (among much other stuff)...

modperl_callback_run_handlers: no PerlChildInitHandler handlers
configured ()

what does this mean, and what do I have to do configure the handlers?

Any ideas anybody?

regards,
