Comment(by nox at macports.org):

 http://www.gnu.org/software/libtool/news.html
 > Despite a new and improved M4 interface to Libtool from Autoconf, every
 effort has been made to retain backwards compatibility with the 1.5.x
 interfaces. Autoupdate (which ships with Autoconf) will help you upgrade
 your configure.ac to the new interface when you are ready to migrate.

 So even if it does break a port, it will be easy to fix the `configure.ac`
 script.
