Глюк с qt

Не компилится тестовый пример в скрипте configure, который проверяет
библиотеку qt. Пути qtdir и прочие прописаны правильно, qt 3.0.4 с
threads gcc 3.1. В чем прикол???


Вот такой кусок появляется в config.log после запуска configure:

Make sure that you have compiled Qt with thread support!
