MediaWiki unit tests are broken in Ubuntu 15.04. Has anybody else encountered and worked
around this problem?
$ php phpunit.php
PHP Fatal error: Class 'SebastianBergmann\Version' not found in
/usr/share/php/PHPUnit/Runner/Version.php on line 74
PHP Stack trace:
PHP 1. {main}() /home/wiki/wiki/wiki/tests/phpunit/phpunit.php:0
PHP 2. PHPUnit_Runner_Version::id() /home/wiki/wiki/wiki/tests/phpunit/phpunit.php:108
$ phpunit --version
PHPUnit 4.2.6 by Sebastian Bergmann.
This is with Mediawiki 1.26.0. Some web searches led me to these tickets from 2014 which
are marked as Fixed, but I don't see an explicit workaround in them:

Thanks for any advice,
