Yesterday, I posted a unofficial patch to rayshade 4.0 patchlevel 6,
but it is incomplete. Here is a new unofficial patch.

In [e-mail]'s mail he writes:

My failure is that I don't know 386BSD's lex is GNU flex! New patch is
as follows. Extract rayshade source, patch this and make.

IMPORTANT!
    The patch in <[e-mail]> is
    incomplete. Don't use it!

  Thanks Mr.Garrett for his report. I hope this patch is perfect.
