errors installing libao

[JazzKartell]

Hi,

I just started using Darwinports and got some problems. I hope you can  
help me...

I tried installing libao  and get an error message. I think there are  
problems with building the paket.

I am using leopard, perhaps that's the problem.

Here is the message:

--->  Building libao with target all
