OS X cgi error

[Richard Miller]

For the heck of it... since there's no documentation I can find on  
the subject, but the error logs are referencing license.rev... I  
stuck a license.rev stack (from Rev 2.5) into the cgi folder. This  
produces an entirely new message in the error log (no longer  
referencing license.rev):

revolution: can't open display
revolution exiting on signal 10
[and then the usual error] premature end of script headers
