Компиляция модуля PHP7 couchbase

я пытаюсь скомпилировать php-couchbase (https://github.com/couchbase/php-couchbase) с PHP7, но после phpize, ./configure на make получает эту ошибку:

Couchbase нам не поможет, а PHP7 важен для повышения производительности. Мы пытаемся с HHVM, но мы не можем скомпилировать модуль couchbase.
