Cdf library compilation fails while installing opendx

[loscotec@…]

I tried to install opendx using the command:

sudo port install opendx 

on a MacBook with Leopard.

Everything goes fine untill it reaches the cdf library. At that time it reports the error:

################################################################

if I try sudo port install cdf it gives the error:

I manually installed all the other depenencies after it and it seems like cdf is the nonly missing one to be able to complete the open dx installation.
