Apache Portable Runtime ======================= If you are building APR from SVN, you need to use a slightly non-standard build process. You must have autoconf and libtool installed for this to work. There are three steps: 1) ./buildconf 2) ./configure 3) make If you are building APR from a distribution tarball, buildconf will have already been run for you, and you therefore do not need to have either autoconf or libtool installed, and you do not need to run buildconf. Skip step one above and just run configure then make.
