Problems after Perl upgrade

I’ve been forwarded this message from a friend of a friend, since I’m by
no means a Perl expert, I thought I’d pass along to the list to leverage
your knowledge.

My initial thought is to reverse the Perl upgrade, but it’s probably
needed for something else. Is this simply a path issue?

I’ve been running RT3 for quite some time now but after a Perl upgrade I
can’t get it to run again. I’ve seen this before but I can’t for the
life of my remember what I did to fix it the last time. Although I know
very little about Perl, everything appears to be in order (Perl 5.8.7)
including HTML::Scrubber. RT3’s test script says everything is fine. But
when I log in I get this:

error:
Can’t locate object method “new” via package “HTML::Scrubber” (perhaps
you forgot to load “HTML::Scrubber”?) at

I also get this when I got the Ticket page:
