Problems with building qt creator

[GreenSnake]

Hello2all

I am trying to buil qt creator from sources. I got the sources of qt creator from "here":http://download.qt-project.org/official_releases/qtcreator/3.0/3.0.0/qt-creator-opensource-src-3.0.0.tar.gz, qt sources from "here":http://download.qt-project.org/official_releases/qt/5.2/5.2.0/single/qt-everywhere-opensource-src-5.2.0.tar.gz and Ubuntu 13.04.

Qt sources unpacked into ~/src/qt-everywhere-opensource-src-5.2.0,
qt creator sources unpacked into ~/src/qt-creator-opensource-src-3.0.0

I am trying to follow "this guide":http://doc-snapshot.qt-project.org/qtcreator-extending/getting-and-building.html

As far as i can understand, it is not needed to build qt itself (qt binary package is installed on my system), but qt creator needs some of qt headers.

My actions:
@
cd ~/src/qt-creator-opensource-src-3.0.0 &&
mkdir build && cd build &&
qmake -r QT_PRIVATE_HEADERS=../../qt-everywhere-opensource-src-5.2.0/include ..
@

And i got the next error:
@Project WARNING: x11extras module not found, raising the main window might not work. (The x11extras module is part of Qt 5.1 and later.)
Project ERROR: Unknown module(s) in QT: script
@
What is correct way to fix it?

(And a little offtopic: how to quote on this forum? When i use Quotes button only bq. mark is added, and it seems it is not work...)

Check that you have in you base system libQtScript.so, [Qt4Script.dll - edit, sorry obviously TS is on x11...] or similar... it can be in different package.

Also maybe installing some-dev package helps.
And you should have headers(not private, but common) on your host.
