PHP Parse error activating plugin

Installed the plugin on 4.7.2 and on activation received this error:

[Tue Feb 07 12:33:50 2017] [error] [client 97.104.76.195] PHP Parse error: syntax error, unexpected T_USE, expecting T_FUNCTION in /home/wordpress/<sitename-removed>/wp-content/plugins/wp-log-viewer/libs/Plugin.php on line 27, referer: https://<sitename-removed>/wp-admin/plugins.php?plugin=wp-log-viewer%2Fwp-log-viewer.php

It’s running Linux (debian squeeze) if that matters.
