Toda vez que tento usar o ports

Como faço para resolver este erro:

Try `ltconfig13 --help' for more information.
configure: error: libtool configure failed
===> Script "configure" failed unexpectedly.
Please report the problem to [email protected] [maintainer] and attach
the "/usr/ports/devel/glib12/work/glib-1.2.10/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`).
