Libtool is a very flexible but relatively slow tool used for a lot of software; it can impose a signicant time penalty during compilation. This post to debian-devel@debian.org names a new tool, dolt, which works as a drop-in replacement for libtool can significantly reduce build time. It’s not (yet) supported on DragonFly.  The name comes from “do ltcompile”.  (from Hasso on EFNet #dragonflybsd)
