Hi again PySide and Guix maintainers,

Thanks for your help so far. After building Shiboken2, Pyside2 and
PySide2-Tools are still required for FreeCAD. In building Pyside2, I get
the error in the attached paste. Clang 6.0.1 and LLVM 6.0.1 are installed
and I have set the CLANG_INSTALL_DIR and LLVM_INSTALL_DIR vars to their
respective paths.  I have also included the package definition in the paste
for the Guix maintainers, if they have any input.

There also seem to be some more issues finding various extra QT libraries
but I'd like to do one thing at a time.

Thanks again for all your help!

- John
