Trying to install libtool-1.4 on mac os x

I usually install php by loading up a preconfigured module for apache. This time though I have reason to build it from cvs with all the goodies I want. It's about time I learned how to do it anyways. The problem though is that in order to build php from cvs you need libtool-1.4 installed.

My version of os x (10.2.6) has library libtool-1.4.2 installed. Php.net clearly states that won't work. I've been able to install the correct versions of automake and autoconf but have had no luck with libtool.

Thanks for any help.
