php70-mongo install doctrine/mongodb-odm fails
<p>I try to install doctrine/mongodb-odm[1.0.5] over composer but drops me </p>

<pre><code>  Problem 1
    - doctrine/mongodb 1.3.0 requires ext-mongo ^1.5 -&gt; the requested PHP extension mongo is missing from your system.

</code></pre>

<p>mongo extension is already installed </p>

<pre><code>php -i | grep mongo

/usr/local/etc/php/7.0/conf.d/ext-mongodb.ini
mongodb
mongodb support =&gt; enabled
mongodb version =&gt; 1.1.6
mongodb stability =&gt; stable
libmongoc version =&gt; 1.3.5
mongodb.debug =&gt; no value =&gt; no value
