Help running git build in custom directory

[tbscope]

I need some help with running a build of a git clone of Qt Creator, installed in a custom directory in home folder.

These are the exact steps I performed. Can someone take a look and tell me if I did something wrong?

tbscope@laptop ~ $ mkdir qtmaster-bin
tbscope@laptop ~ $ mkdir qtcreatormaster-bin
tbscope@laptop ~ $ mkdir qtcreatormaster-build
tbscope@laptop ~ $ mkdir qtgit
tbscope@laptop ~ $ cd qtgit
tbscope@laptop ~/qtgit $ git clone git://gitorious.org/qt/qt.git
tbscope@laptop ~/qtgit $ git clone git://gitorious.org/qt-creator/qt-creator.git
tbscope@laptop ~/qtgit $ cd qt
tbscope@laptop ~/qtgit/qt $ ./configure -no-glib -no-gtkstyle -declarative -debug -no-webkit -developer-build -prefix /home/tbscope/qtmaster-bin
tbscope@laptop ~/qtgit/qt $ make -j2
tbscope@laptop ~/qtgit/qt $ make install
tbscope@laptop ~/qtgit/qt $ cd ../../qtcreatormaster-build
tbscope@laptop ~/qtcreatormaster-build $ /home/tbscope/qtmaster-bin/bin/qmake /home/tbscope/qtgit/qt-creator/qtcreator.pro
tbscope@laptop ~/qtcreatormaster-build $ make -j2

tbscope@laptop ~/qtcreatormaster-build $ cd ../qtcreatormaster-bin
tbscope@laptop ~/qtcreatormaster-bin $ cd bin
tbscope@laptop ~/qtcreatormaster-bin/bin $ ./qtcreator

I already tried the following things:
* I removed a Qt Creator 1.3.1 install so all the plug-ins are definatly from my build of Qt Creator
* I added a qt.conf document in the ~/qtcreatormaster-bin/bin folder
* I checked my paths. ~/qtmaster-bin/bin and ~/qtcreatormaster-bin/bin are in $PATH
* I used ldd to check most of the executables and libraries (not all though). All those checked seem to call the correct Qt libraries.

I have no idea how to solve this.
Does anyone else have any ideas?

Thanks

Edit: Thinking about it a little bit:
I think it is a program or library outside my build of Qt and Qt-Creator that makes use of Qt-4.6.3.
Or, since I didn't compile Qt Webkit from the git clone, and there is a Qt webkit 4.6.3 installed, something calls this library. Although I think this is highly unlikely.

After completely removing Qt-4.6.3, I got this error/warning when starting Qt Creator (it does start now)

QSqlDatabase: QSQLITE driver not loaded
QSqlDatabase: available drivers:

I guess Qt Creator tried to use Qt-4.6.3 sql drivers.
Since my install of Qt-4.7.0-git does contain the sqlite sql driver, I don't know why it doesn't find it.

I got it now.

After a weekend of trial and error, I redid everything in a clean environment, and it all worked out of the box.
