configure: error: libtool configure failed
===>  Script "configure" failed unexpectedly.
Please report the problem to ports at FreeBSD.org [maintainer] and  
attach the
"/var/build/ports/graphics/aalib/work/aalib-1.4.0/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`).
