all of this makes me think that you're after things like $ENV{REMOTE_USER}
and other CGI environment variables?
in general, <Perl> sections within a httpd.conf are executed when Apache is
started. that means that there is no request to associate with a client, so
no $ENV{REMOTE_USER} or other things make any sense. that's also why you
couldn't call $r->subprocess_env or $r->parsed_uri - there is no $r at
config time.
so, if it's these environment variables you're looking for, you'll need to
take a step back and assess what you're really trying to do.
if you're after other things - such as variables from /etc/profile - but
can't access them in <Perl> sections that's a different issue, and something
that I'd need to try and recall, as I thought they should be visible at that
point.
