Issue with Calendar after install of 3.8.7


I am testing at present migrating my system from RT 3.6.5 to 3.8.7.

To fill you in on details I did this by:

  1. Installing 3.8.7 on new RHEL 5 server

  2. copying database from live system to Test system

  3. running all the database and schema updates to test system.

  4. migrating to ExternalAuth module to enable LDAP logons.

  5. Moving across all local customizations of pages.

In the process of testing the new test server I have come across an issue with the Calendar module.

In the dates section of a ticket if I use the calendar link I get the following error:

Can’t locate object method “new” via package “DateTime” at /usr/lib/perl5/site_perl/5.8.8/Calendar/ line 87.

I have DateTime module installed and it is linked to the correct version of Perl.

   Wed Dec 16 14:58:26 2009: "Module" DateTime

   ·   "installed into: /usr/lib/perl5/site_perl/5.8.8"

   ·   "LINKTYPE: dynamic"

   ·   "VERSION: "

   ·   "EXE_FILES: "

Any help would be most appreciated
