Install Error

[Peter Hindrichs]

I am looking to further my understanding and knowledge of the command  
line and "Ports"  so when I tried to install the port "CosmicDebris" I  
got this message.

I have tried to figure it out, but am having no luck, could someone  
please help me to understand what is actually being said here. Could  
this have something to do with the fact that the program is not Snow  
Leopard compatible  or is there another reason ?
