I don't understand completely what you are saying with "trashed".
The output looks a bit better for me. I tested with iCab and NetScape
4.7 + WebStar though.

GATEWAY_INTERFACE => CGI/1.1
MACPERL => Fressplatte:Programme:MacPerl Ä:
REMOTE_ADDR => 128.128.18.103
SERVER_PROTOCOL => HTTP/1.0
HOME => Fressplatte:Programme:MacPerl Ä:
REQUEST_METHOD => GET
HTTP_USER_AGENT => iCab/Pre1.7 (Macintosh; I; PPC)
HTTP_ACCEPT => image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, image/xbm, image/png, */*
TMPDIR => Fressplatte:Temporary Items:
HTTP_ACCEPT_LANGUAGE => de
SCRIPT_NAME => /tests/testcgi.acgi
HTTP_PRAGMA => no-cache
SERVER_NAME => mac5.wmd.de
SERVER_PORT => 80
HTTP_HOST => mac5.wmd.de
USER => Axel
PERL5LIB => Fressplatte:Programme:MacPerl Ä:site_perl

I suppose it has to do with not masking '>'. You should write:
   print "$key =&gt; $ENV{$key}<br>\n";

Some browsers slurp this HTML syntax error, others don't.
All the other non alpha-numerical characters should be
encoded as well. (I like the "Ä" especially as in "Ärger" :))

For checking HTML syntax I very much like to use iCab, an alternative
and very elegant browser which features an integrated check utility.
See http://www.icab.de/ It's just a 2MB single file application.


Many regards
