QT2.x project--tarball doesn't compile

[M.H.]

Hi,
I created a QT2.x SDI project, that works without a problem (in Kdevelop).
When I try to make/install this app from the tarball (created with "make distribution"
from the "project" menu), I run into some errors at link time (undefined references),
because the .moc files are not created/compiled/linked (doing a configure, make).
Can someone tell me whats wrong? Shouldn't the .moc files be created 
automatically?
Thanks!
