OS X cgi error

[Richard Miller]

I'm sure there's an answer somewhere in the archives, but I can't  
find it.

Trying to run Rev cgi on an Intel Mac, 10.4.10. Using the sample  
"hello.cgi" script. Downloaded the Darwin engine, as per the  
instructions at the Rev web site. All permissions are set to 755.

Error log says:

revolution: Can't load stack or script  license.rev
Premature end of script headers: /Library/WebServer/CGI-Executables/ 
hello.cgi

What's the solution?

Thanks.
