[Plugin: Simple Real Estate Pack] Fatal Error when Activating Plugin

When I try to install this plug in I am getting a fatal error, here are the error details.

Plugin could not be activated because it triggered a fatal error.

Parse error: syntax error, unexpected T_STATIC, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or ‘}’ in /hermes/bosweb/web236/b2369/sl.wadefoli/moonit-sandbox/wp-content/plugins/simple-real-estate-pack-4/Class_srpWidgets.php on line 4

Has anyone experienced this and have a fix?

Thanks,
Wade
