Thank you so much! Whew what a journey.
I am glad that the union package of llvm and clang could be separated. When I was working on the package in the very beginning pyside2 would not build without clang and llvm living in the same parent directory.
I did just run the program and it does not look like it is functioning the way it should. With the last patchset I submitted, it did work properly. I will investigate...
Thanks again, it's been a real pleasure working with you.
