if you -read- the output carefully, you discover that it is complaining 
abouot not being able to find an include file. a file named:
   xen/sys/privcd.h

You need to figure out _where_ that file is on your system, and arrange
to include the parent directory in the 'include search path' when you
compile that module.   the cc '-I" flag.
