I'm not sure how current it is, but it's working for me on RT 3.4

Essentially I created a file in the local/share/request-tracker3.4 tree 
called html/Callbacks/CCDC/Ticket/Elements/ShowMessageStanza/Default
containing:

<%init>
my $val = $$content;
use bytes;
$val =~ s/(s?http|https):[\w\/\.:+\-]+/<a href="$&">$&<\/a>/gi;
$$content = $val;
</%init>
<%args>
$content => undef
</%args>


If you capture anything in the <regexp>, you can use $1, $2, ... in the 
replacement, as well as $& for the whole matched string.

$val =~ s;(bug|bz|bugzilla)\s*(\d{4,6});<a 
href="http://bugzilla/show_bug\.cgi\?id=$2">$&</a>;gi;

would turn "bug 1234" into a clickable link.
