[Qt-interest] building QT fails

[Lorenzo Marussi]

hello,

I have a strange error building Qt4 from scratch.

I have a Gentoo O/S, and Qt-Core and other qt components build fine and 
I run it successfully.

But, now, to enable Qt/3D 
(http://doc.qt.nokia.com/qt3d-snapshot/qt3d-building.html),
I have to build Qt from scratch.

I follow this doc: http://doc.qt.nokia.com/4.7/install-x11.html
I download the qt-everywhere-opensource-src-4.7.3.tar.gz tarball, I made 
"./configure -opengl" successfully, but "make" return with this error:

`/usr/src/build/qt/qt-everywhere-opensource-src-4.7.3/src/dbus'

I alredy checked that I have all requirements in my system 
(http://doc.qt.nokia.com/4.7/requirements-x11.html)

What I miss? some ideas?

Thanks,

Lorenzo
