Please report the problem to ade@FreeBSD.org [maintainer] and attach the
"/usr/ports/devel/libtool15/work/libtool-1.5.22/config.log" including the
output of the failure of your make command. Also, it might be a good idea to
provide an overview of all packages installed on your system (e.g. an `ls
/var/db/pkg`).
