Install V8JS extension under Win7 installation Mac:mac

Recently interested in the V8 JavaScript engine, found that PHP has a v8js extension, on its own MacBook Air mounted a play, recording the installation process.
1. Install V8 Javscript engine. Follow the instructions on the wiki http://code.google.com/p/v8/wiki/BuildingWithGYP on the V8, and there is basically nothing wrong with that.
SVN checkout V8 source code
$SVN Checkout Http://v8.googlecode.com/svn/trunk/v8
$CD V8
This version of V8 needs to be installed with Gyp, not knowing what it is, but just the following command
$make dependencies
Native indicates that the release version of the current system is compiled, and library=shared indicates that the dynamic link library is compiled
$make native library=shared
Copy the included files and out directories under the V8 directory to the system directory
$sudo CP include/*/usr/local/include
$sudo CP out/native/*/usr/local/lib
2.mac default PHP installation no pear, but with the installation file, run it and put Pear
$CD/usr/lib/php
$sudo PHP Install-pear-nozlib.phar
3. Install V8JS, I install the version is the beta version need to add channel
sudo pecl install V8js channel://pecl.php.net/v8js-0.1.3
