Hello.
I tried to static-qt build with 5.0.2 in Windows7 64bit environment.
It seems to suceed in building but failad to install.

Console says:
-> qt-5.0.2
--> download qt-everywhere-opensource-src-5.0.2 ... done
--> unpack... done
--> patching...done
--> configure... done
--> building...... done
--> installing......error 2!

All I did was:
1)Extracted msys+7za+wget+svn+git+mercurial+cvs-rev11.7z to c:\msys
2)Launched mingw shell
3)cd && git clone git://github.com/Alexpux/Qt-builds.git
4)cd Qt-builds
5)git checkout develop
6)./buildall x32 --opengl-desktop --static-qt
