Cant install zend-mail, because zend-mime depends on zend-stdlib: ~2.5

I have installed zend-stdlib 3.0.
Running composer require zendframework/zend-mail I get

Sorry for the first report, hit enter accidentally...

Why do you want to use Zend\Stdlib 3.0 together with Zend\Mail 2.x?

[rommsen]

Because the app I am working on happens to have Zend\Stdlib 3.0 installed. I just want to install Zend\Mail which has no problem with Zend\Stdlib 3.0 but it also depends on Zend\Mime which requires ~2.5.

How should I do it?

[weierophinney]

For now, composer require "zendframework/zend-stdlib:^2.7". We'll update zend-mime soon to support v3.

Fixed with #9; release will be cut shortly.
