apache, when it runs a process that generates the stuff that'll
be sent out to a client's browser, checks the text for
completeness. this includes all the header fields, such as
content-type: text/html
connection: close
date: 27 nov 2000
accept-ranges: bytes
try this, now:
telnet localhost 80 ^M
GET / HTTP/1.1 ^M
^M
<localhost> is whatever host your server's running on;
the ^M merely denotes end-of-line/enter on your part.
here's what you'll get back:
HTTP/1.1 200 OK
Date: yada-yada
that first line is the STATUS for the whole request,
which comes even before the header:value fields.
so try this in your script:
#!/usr/bin/perl
print "HTTP/1.1 200 OK\nContent-Type: text/html\n\n";
print "<b>hello world</b><p>it worked!";
so what you're seeing is APACHE noticing that you
didn't specify a HTTP STATUS CODE.
from the perl.apache.org/guide/ website--
If you take a basic CGI script like this:
print "Content-type: text/plain\r\n\r\n";
print "Hello world";
it wouldn't work, because the HTTP header will not be sent
out. By default, mod_perl does not send any headers itself.
You may wish to change this by adding
PerlSendHeader On
in the Apache::Registry <Location> section of your
configuration. Now, the response line and common headers
will be sent as they are by mod_cgi. Just as with mod_cgi,
PerlSendHeader will not send the MIME type and a terminating
double newline. Your script must send that itself
the modperl guide (perl.apache.org/guide) offers a wealth of
info, once you know what you're looking for... :)

you need
# something along the lines of...
LoadModule userdir_module /usr/lib/apache/1.3/mod_userdir.so
UserDir /home/*/public_html
<DirectoryMatch ^/home/.*/public_html/cgi-bin>
Options +ExecCGI
</DirectoryMatch>
UserDir disabled root
somewhere in your config, then.
