Rather neat. Couple of minor suggestions. The first is mainly because it needs at least one char to search for (or it dies voluminously which 2 > is also designed to fix). If you used a var rather than the hardcode name the script is renamable. 

- uri_unescape($ENV{QUERY_STRING}) =~ /^([\w\s:-]*)$/
+ uri_unescape($ENV{QUERY_STRING}) =~ /^([\w :-]+)\z/

- exec "perldoc -u $1|pod2html --header --title='$1'";
+ exec "perldoc -u $1|pod2html --header --title='$1' 2>/dev/null";

You don't really need the fork..... 

#!/usr/bin/perl -w
use strict;
use URI::Escape;
$|++;
$0 =~ m!([^/\\]+)$!;
my $script = $ENV{SCRIPT_NAME} || $1 || 'perldoc.cgi';

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

$ENV{QUERY_STRING} or error( "Usage $script?command<br>Try $script?per
+ldoc\n" );

uri_unescape($ENV{QUERY_STRING}) =~ /^\s*([\w :-]+)\s*\z/
    or error( "Bad query string: '$ENV{QUERY_STRING}'\n" );

chdir '/tmp';

open DOC, "perldoc -u $1|pod2html --header --title='$1' 2>/dev/null |"
    or error( "Could not exec perldoc or pod2html. $!\n" );

while (<DOC>) {
    s{href="/([^."]+)\.html}
     { local $_= $1; s|/|::|g; qq!href="$script?$_! }gei;
    print;
}
close DOC;

sub error { print "Error: ", shift; exit };
