Redsleeve is the arm port of Centos 6. So I am installing from the tar from roundcube.net and the installer script reports that:

Checking PHP extensions

The following modules/extensions are required to run Roundcube:

DOM: NOT OK(Could be loaded. Please add in php.ini; See http://www.php.net/manual/en/book.dom.php)

The next couple of extensions are optional and recommended to get the best performance: FileInfo: OK

Mcrypt: NOT AVAILABLE(See http://www.php.net/manual/en/book.mcrypt.php)
Intl: NOT AVAILABLE(See http://www.php.net/manual/en/book.intl.php)

I don't see in the manual what to add to php.ini. Please advise.

I have tried to find mcrypt (yum install mcrypt libmcrypt), but these are not the mcrypt it seems to want.

And I don't know were to find the intl.php.

thank you
