Most CGI-related errors that you get from Perl scripts will be of the
"script returned inappropriate headers" variety.  These are often due to
STDERR messages generated early in the script due to failures to load
modules, etc.  IMHO the easiest way to solve these kind of errors is to
return a valid set of HTTP headers early in the script.

The trivial HTTP header from perl is:

	print "Content-Type: text/html\n\n";  # Note the blank line

The other reason for this error would be a syntax problem, which can be
checked on the command line with a perl -c.

If you still get the same error from a browser, it is almost always
permissions.

Cheers,
Dave
