qtscriptgenerator bindings

I am trying to compile and use qtscriptgenerator bindings. Following the README instructions i was able to successfully step 1(qmake and nmake generator). However when trying to run generator.exe in release folder gives fatal error: unable to parse typesystem_core.xml
trying to compile bindings from here on gives error. Any idea what I should do. I tried downloading both 4.6 and master version from git and tried compiling both with VS2008 and mingw compiler but same error appears. Any one who has done it before? Please help...
