What is the difference between the ada and gnuada variants? It looks  
like the ada variant uses an ada compiler provided by MacPorts (if  
so, there should be a dependency on a MacPorts port in that variant),  
and the gnuada variant uses an ada compiler provided by someone else  
in binary form which installs into /opt/local? If that's correct,  
then that's very disconcerting; we should not be encouraging users to  
install something that puts files into /opt/local without using  
MacPorts to do so. And the gnuada folks should not be distributing  
binaries that install things into the MacPorts /opt/local prefix.
