Setting up GStreamer Build environment on Windows bootstrap failure

[David Wells]

When running bootstrap I getting following error:

File C:/Users/user/cerbero/mingw/w32/mingw-w32-gcc-4.7.3-windows-x86.tar.xz already downloaded.
Unpacking C:/Users/user/cerbero/mingw/w32/mingw-w32-gcc-4.7.3-windows-x86.tar.xz in C:/Users/user/cerbero/mingw/w32
Running command 'tar -Jxf /C/Users/user/cerbero/mingw/w32/mingw-w32-gcc-4.7.3-windows-x86.tar.xz'
C:/MinGW/bin/xz.exe: error while loading shared libraries: liblzma-5.dll: cannot open shared object file: No such file or directory
tar: Child returned status 127
tar: Error is not recoverable: exiting now

For complete output see attached file BootStrap.txt

Note: I originally got below error and I manually down loaded file, by using pasting ' http://gstreamer.freedesktop.org/data/cerbero/toolchain/windows/mingw-w32-gcc-4.7.3-windows-x86.tar.xz ' in my web browser and copied file to 
'C:/Users/user/cerbero/mingw/w32/mingw-w32-gcc-4.7.3-windows-x86.tar.xz'
Once this was done I get error describe and found in BootStrap.txt.
