[horde] weatherdotcom.php Fatal Error

[ken_faris@sbcglobal.net]

Hi, any ideas why changing from weatherdotcom.php version 1.37.4.8.2.3 which
I never could make work.  To weatherdotcom.php version 1.37.4.13 would cause
the following error: 
Fatal error: Cannot redeclare class horde_block_horde_weatherdotcom   (error
declared as Line 18 which is exactly the same as the old Line 18)
 
I am using latest stable release of Horde
 
Thanks,
Ken
