Ant "optional tasks" installation

Hi,
I?m trying to install the adigres archive system on a trustix 2.2 box. 
Installing ant works without any flaws. One of the aditional 
requirements are the 1.6.5 "ant optional tasks". All I could find was a 
debian package, at the ant homepage there is a link to a collection of 
additions but I?m pretty unsure if I all need them. Has anybody ever 
installed ant 1.6.5 + optional tasks on trustix 2.2 and could give me a 
hint?

Best regards,

  Mike
