cvsweb download problem

[David Everly]

I have the latest cgi script from http://www.idaemons.org/~knu/cvsweb/
and am running it with cvs 1.11.1p1 and rcs 5.7 on sun solaris 2.8
with iplanet enterprise server 6.0SP1.

Everything seems to work (including annotate), with the exception of
clicking on a revision or download link.  When accessing these links,
the following message occurs:  "Error: Unexpected output from cvs
co:", followed by the contents of the file in one long string, with no
formatting.  This is displayed in the browser window.  How can I fix
this?

Thanks,
Dave.
