Conflicto entre pluguins jQuery

[biko8]

Hola,

Estoy haciendo un sitio en drupal. Y ahora estoy intentando poner este pluguin de jQuery: (http://www.dynamicdrive.com/dynamicindex4/powerzoomer.htm)

Pero al incluir el archivo (ddpowerzoomer.js) que mencionan en la pagina, que contiene el pluguin me entra en conflicto con otro existente de ubercart.

Me pregunto si podria modificar el codigo de (ddpowerzoomer.js) para que no entrara en conflicto, alguien podria hecharme una mano para modificarlo y poder llamar al pluguin de otra manera?

El error que me da de js es este:

Código:

Error: $ is not a function
Archivo de origen: http://192.168.1.10:81/DEV/4pek/sites/all/modules/ubercart/uc_file/uc_file.js?e

El contenido del archivo (ddpowerzoomer.js) es este:

Código:
