如何在Mac OS X 10.6上升级到Autoconf 2.6.2或更高版本？

Question

My environment is Mac OS X 10.6. I have installed Autoconfig using MacPorts:

sudo port -v selfupdate
sudo port install autoconf

But the autoconf installed is 2.6.1. My question is how can I upgrade it to 2.6.2?

The program I am trying to compile need autoconf 2.6.2

configure.ac:14: error: Autoconf version 2.62 or higher is required
/opt/local/share/aclocal-1.11/init.m4:110: AM_INIT_AUTOMAKE is expanded from...
configure.ac:14: the top level

aclocal-1.11: autom4te failed with exit status: 63

I usually do not bother installing any of the autotools on the system, but install them in $HOME instead. Just grab the autoconf tarball from http://ftp.gnu.org/gnu/autoconf/ , unpack it and run:

./configure --prefix=$HOME
 make
 make install

Make sure $HOME/bin is in your PATH before the system dir, or uninstall autoconf from the system.
