Yet again I'd like to point out, that -- contrary to the wide-spread 
practice -- ports should not, by default, list a particular shlib major 
number in LIB_DEPENDS. Only in cases, when a wrong version of some 
libfoo is known to cause problems, should the correct version be 
explicitly given in LIB_DEPENDS.
