[pm-h] mod perl and calendar.cgi

Tue May 6 08:53:55 PDT 2014

Some progress, but still not working.

Turns out that the problem file "calendar.cgi" was using a locally installed 
liteweight version of template.pm.

I renamed the file CalTemplate.pm and put it into the site/lib/HTML folder.
I changed the package name in this file to CalTemplate.pm

The %INC shows:
For HTML/CalTemplate.pm value is C:/Perl/site/lib/HTML/CalTemplate.pm

The use statement in calendar.cgi is
use HTML::CalTemplate;

The use directive finds and appears to load the file, but the same line as 
before can't find initialize
[Tue May 06 10:15:30 2014] [error] Can't locate object method "initialize" 
via package "HTML::CalTemplate" (perhaps you forgot to load 
"HTML::CalTemplate"?) at 
D:/www/wc-admin.com/cgi-bin/event_calendar/calendar.cgi line 131.\n

The offending line 131 is
my $tmpl = CalTemplate->initialize( $directives->{'template'} || 
'calendar.html' );

Obviously, my understanding about mod_perl and now OOP is limited, so any 
comments?
