Apache showing Perl code

[B.J. Faught]

I just installed Apache and mod_perl, but for some reason when I execute
scripts through my Apache server it shows all of the Perl code:

#!C:/Perl/bin/Perl.exe
print "Content-type: text/html\n\n";

foreach $var (sort(keys(%ENV))) {
    $val = $ENV{$var};
    $val =~ s|\n|\\n|g;
    $val =~ s|"|\\"|g;
    print "${var}=\"${val}\"\n";
}

I got the path found on the first line from an example Perl script
(printenv.pl) that came with the latest version of the Apache server.

Could anybody give me a hand with a suggestion or two?
