Premature end of headers can mean a wide variety of things, especially with a perl script.

Your best bet is to contact the script vendor and have them install the scripts for you instead of trying to do it yourself.

If you can get to your error logs, you can run the script from the command line. Telnet/SSH in to your server, get in the directory of the script, type perl scriptname.cgi and watch what happens, it may give you a clue.

99% of the time, "premature end of script headers" means that the script is throwing an error and sending output before the client browser has gotten the "Content-type: text/html\n\n" header. Try running the cgi from the command line to see the errors, or just put the line

print "Content-type: text/html\n\n"

at the start of the script so that the errors will print out to the browser window.
