Yes. Firefox, LibreOffice/OpenOffice come to my mind directly. There  
may be others. I expect those to be rare (compared to the size of the  
ports collection), but if you encounter some false positives, it's  
probably a big package. Either way, "locate $missing_lib" is a good  
idea here.

Temporary for the run of this check, yes.

Bye,
