Установка текстового редактора

Я пытаюсь запустить редактор электронного текста. Я прочитал http://www.e-texteditor.com/forum/viewtopic.php?p=14953#14953 и компилирует редактор электронных текстов на Linux. Но на моем 10.04 Lucid он не работает на следующем шаге:

./ build_externals_linux.sh debug

со следующими сообщениями об ошибке:
