Failure to find: ../skin.cpp

Hi!

I just tried installing QT 4 on Ubuntu 8.04. I downloaded qt-x11-opensource-src-4.4.3.tar.gz, unpacked it and started ./configure. At the end of it it says:

WARNING: Failure to find: ../skin.cpp
WARNING: Failure to find: ../skin.h
for /home/cruz/qt-x11-opensource-src-4.4.3/tools/xmlpatterns/xmlpatterns.pro


I installed the same version on a different machine earlier today (also Ubuntu 8.04) and it worked like a charm. How come these files are missing now?

Thanks
Cruz
