This is the current workaround on the DarwinPorts portfile for GNU  
Prolog: use gcc 3.3 instead of the default gcc 4.0. However, there is  
no need to manually replacing/changing soft links. Apple provides a  
command that allows you to set the default version of the gcc  
compiler. Just type:

    % man gcc_select

to lear how to use it.

Cheers,

Paulo
