How do I enable a PHP extension (like mcrypt)?

[johnRivs]

This is what I have in environment.yaml:

os::packages:
  php5-mcrypt: true

I tried that alone and

php::builds:
  5.6.0:
    installed: true
    default: true
    variants: dev
    extensions:
      xdebug:
        enabled: true
        version: stable
      mcrypt:
        enabled: true
        version: stable
      xhprof:
        enabled: true
        version: latest
    fpm:
      port: 9002
      autostart: true

It says:

==> default: PHP Warning:  PHP Startup: Invalid library (maybe not a PHP library) 'mcrypt.so' in Unknown on line 0
==> default: /opt/phpbrew/bashrc: eval: line 126: syntax error near unexpected token `('

Now I removed those lines and it thinks I'm still trying to install mcrypt. So I do vagrant ssh and can't even do a ls because I just get:

PHP Warning:  PHP Startup: Invalid library (maybe not a PHP library) 'mcrypt.so' in Unknown on line 0

After not using the config file, then using it again, it outputs a bunch of errors about letting stuff unconfigured. What a mess :/

Enabling extensions for system php version is bit different than enabling extensions for phpbrew php versions. In order to enable an extension for system php, use the OS package manager to install and enable the extension. In case of mcrypt you can use:

os::packages:
  php5-mcrypt: true

In order to enable an extension for a php version installed by phpbrew, use the variant for this extension if there is one (check the available variants) and if there isn't one, define it using the extensions: directive. In case of mcrypt, there is a phpbrew variant for it, can use:

php::builds:
  5.6.0:
    installed: true
    default: true
    variants:
      - dev
      - mcrypt
    extensions:
      xdebug:
        enabled: true
        version: stable
      xhprof:
        enabled: true
        version: latest
    fpm:
      port: 9002
      autostart: true

Make sure to upgrade your working copy to the latest version 0.2.1
