That's true.  But you probably don't want $stdout to go to a file as
that will cause your script to send no data to the user's browser.

One of the problems that could cause the script to work locally but fail
remotely is leaving off the
	print "Content-type:  text/html\n\n"  # or "text/plain", or
					      # whatever
Both of the \n's are important, as that's how the server and browser
determine when the header stops and the content begins.  From the error
message you gave, it would appear that that's exactly what the problem
is.  Apache executes the script and runs all the way to the end, and,
finding no '\n\n', interprets the body as the header and can't figure
out where the header ends.

Since (iirc) Apache runs on OSX, you could set it up locally and use
that to debug your scripts before uploading them.

Would you mind posting your script?
