Completely useless... it catchs stuff I know for a fact has no direct
dependancy on libtool15... for example I am the author (but not the
maintainer but I helped in the port creation) of devel/thistest and
the *ONLY* direct dependancy it has is java/jdk16 it still lists
libtool-1.5 as a depend in INDEX-8
