Answer 1

You have to enable intl extension from php.ini
if you use xampp see this
Otherwise find php.ini
search intl.dll
remove semiclone infront of it (for xampp)
remove # (for wampp)
Save it and restart server
After this process try to download again

I run into the same problem while installing CakePHP for a new project. What I did was the following:
1) Upgrade the PHP to 5.6 (http://coolestguidesontheplanet.com/upgrade-php-on-osx) and check my phpinfo() file for intl to be enabled. As it was enabled I thought that the default Mac OS PHP in use was not the one I was checking in phpinfo(). Indeed when prompting on the terminal php -v or which php I realised the CLI was using PHP 5.5.3 so I modified my ~/.profile and ~/.bash_profile...
2)vim ~/.profile
#export PATH=/opt/local/bin:/opt/local/sbin:$PATH
PATH=/usr/local/php5/bin:$PATH
3) source ~/.profile
4) vim ~/.bash_profile
#export PATH=/opt/local/bin:/opt/local/sbin:$PATH
export PATH=/usr/local/php5/bin:$PATH
5) Close and reopen the terminal.
6) Check again php -v or which php and PHP 5.6 appeared.
7) Run again php composer.phar create-project --prefer-dist cakephp/app app_name and the error was gone.
It turns out that some months ago I had installed homebrew and with it another PHP version got installed as the default Mac OS PHP with no intl enabled.
