Dear Mark,
 Guess what!
I've removed the leading spaces of the 66, 69, and 72nd lines. Then issued
' make newunix'.
I did not have any error messages. And I've got the following files generated.

  /user3/prof/jjkim/temp/povray31/source/unix >ls -tla pov*
-rwxr-xr-x   1 jjkim    prof     1064960  1-17 17:34 povray
-rw-r--r--   1 jjkim    prof       46760    1-17 17:34 povray.o
-rw-r--r--   1 jjkim    prof       20126  11-22 10:08 povray.1   (and povrayrc
also)

Following lines are shown upon the screen, when I issued 'make newunix'.
Am I close to the final? Do I simply issue 'povray' for running the program?

Thank you so much,

Jong
