I uploaded 0.6.3 release, you can get it here:
https://github.com/vslavik/xmlwrapp/downloads
It contains some cherry-picked fixes for bugs and build issues and doesn't break API or ABI compatibility, so it's a drop-in replacement for 0.6.2. More substantial changes from the 'master' branch will be included in 0.7.0.
