vt7 dev release - Warnings displayed, and unable to perform a clean install on Ubuntu 16.04 Server LTS (php7)

These warnings, displayed on the Step 3 screen of a clean installation, are a little unusual, especially the "line 0" reference?

Warning: Declaration of Users::saveentity($module) should be compatible with CRMEntity::saveentity($module, $fileid = '') in /var/www/html/vtiger/modules/Users/Users.php on line 0

Title changed from vt7 dev release - Warning displayed on clean install on Ubuntu 16.04 (php7) to vt7 dev release - Warnings displayed, and unable to perform a clean install on Ubuntu 16.04 Server LTS (php7)

On the final step to install the install just died. Once you click next on the attached screenshot, for a very brief period, you see the "Installing vtiger2 green bar thing... But that then disappears and nothing else happens. the database does not get built and the script would appear to simply terminate silently. No other errors are reported from what I can see.

I got the installation to complete.

The install silently failed because one, or more, of the following packages was missing but none of these were checked for during the early installation screens:

php7.0-bcmath php7.0-intl php7.0-mbstring php7.0-mcrypt php7.0-xml php7.0-xsl php7.0-zip

Since I downloaded the most recent pull from github, I am no longer able to get a clean installation to run to completion on PHP7. It fails pretty quickly with "Result is not an object".

This is the same server, nothing else changed, as the previous comments.
