I tried this just now.  My attempt failed to configure, because the LLVM test
program failed to compile, because some header file seems to be missing, or
path misconfigured, or something (as yet undiagnosed).

Attached is the error that I get, copied from "config.log".  Is is the same as
the error that you see, John?

Eric.
