Call to undefined method RdKafka\Producer::oauthbearerSetToken() on 6.0.5

[acb]

Description

I have updated to 6.0.5, which has oauth support according to the release docs and other issues on here. I updated librdkafka with yum install librdkafka-devel then ran the pecl upgrade. Everything's fine there, 6.0.5 is installed.

However, when I try to use any oauth functions on my producer they fail.

$conf = new \RdKafka\Conf();
$conf->setOauthbearerTokenRefreshCb(function () {
    $this->setProviderOauthToken();
});
-------------------------------------------------------------
Call to undefined method RdKafka\Conf::setOauthbearerTokenRefreshCb()

$producer = new \RdKafka\Producer($conf);
$producer->oauthbearerSetToken(<valid token stuff>);
--------------------------------------------------------------
Call to undefined method RdKafka\Producer::oauthbearerSetToken()

PHP was not running when I did the upgrade, and for good measure I rebooted the machine after the upgrade was done. What am I missing? How can 6.0.5 be installed but the methods that it contains aren't present?
