[rt-users] RTIR - Installation Issue - YAML.pm path missing in @INC at Apache Startup

[Ruslan Zakirov]

Either install YAML perl module using the cpan shell or in
lib/RT/IR.pm replace the following two lines

            use YAML;
            $RT::Logger->crit( "$self is not a ticket object like I expected"
                    . YAML::Dump($self) );

with

            $RT::Logger->crit( "$self is not a ticket object like I expected");

Will be fixed in RTIR 2.4.2
