qt-creator-2.3.1: install problem

Hello,

I downloaded qt-creator-2.3.1-src.tar.gz and extract it.
Then I did:
qmake qtcreator.pro
make
make install

After a while I got the following error:

install -m 644 -p /home/zvivered/GNU/qt-creator-2.3.1-src/share/doc/qtcreator/qtcreator.qch /share/doc/qtcreator/
install: cannot stat `/home/zvivered/GNU/qt-creator-2.3.1-src/share/doc/qtcreator/qtcreator.qch’: No such file or directory
make: [install_inst_qch_docs] Error 1 (ignored)
install -m 644 -p /home/zvivered/GNU/qt-creator-2.3.1-src/share/doc/qtcreator/qtcreator-dev.qch /share/doc/qtcreator/
install: cannot stat `/home/zvivered/GNU/qt-creator-2.3.1-src/share/doc/qtcreator/qtcreator-dev.qch’: No such file or directory
make: [install_inst_dev_qch_docs] Error 1 (ignored)

What am I doing wrong ?

Thanks,
Zvika.
