PHP mcrypt installing and setting up laravel environment issues

Question

I am using Mac OS X Lion 10.7.5 and I want to clear one thing I do not want to use XAMPP, MAMP anymore.

So I enabled apache, php and installed mysql following this link. This work well. Then I downloaded laravel and installed it following this link. I copied laravel folder inside Sites folder which I created according to first link tutorial. Now when I click on public folder inside laravel folder it gives me following error

Unhandled Exception

Message:

Call to undefined function Laravel\mcrypt_create_iv()
Location:

/Users/zafarsaleem/Sites/learning-laravel/laravel/crypter.php on line 36

Then checked whether mcrypts are installed in phpinfo(). They are not there. To install mcrypt I followed this link. It worked until when I followed to PHP Extension title. When I downloaded PHP 5.3.8 is now the default since Mac OS X 10.7.3 unpacked and when I issue phpize command it gives me this error

Cannot find config.m4. 
Make sure that you run '/usr/bin/phpize' in the top level source directory of the module

What does this top level source directory of the module means? How can I make mcrypt install properly to make laravel work? Please help.

Solution

You will need to install Xcode and the command line tools extra package within Xcode, for then to install mcrypt
