Mod_perl errors

My RT3 has stopped working due to mod_perl being upgraded. I now have to
remove the lines from my httpd.conf file relating to rt:

PerlModule Apache::DBI
PerlRequire /opt/rt3/bin/webmux.pl

<Location /rt>
SetHandler perl-script
PerlHandler RT::Mason

or my httpd process fails to start. The error that I get is the following:

/usr/sbin/httpd start: httpd could not be started

To the best of my knowledge (limited), it looks like this is trying to find
a feature from mod_perl2 even though I am using mod_perl 1.29 and apache
1.33.

If anyone has any ideas as to what is causing this, please let me know.

Thank you.
