Ah, but when you run this code and the env var isn't defined - you get a 
broken script that dies on an undeclared var (a la strict and warnings). I 
added the defines to keep it from choking for those of us that don't have 
ENV{TMPDIR,ftp_proxy,http_proxy} set. These are the vars portage and cpan use 
if defined - but if not defined, they don't care - but when trying to set 
values (and under use strict) we need someway of dealing with them not even 
existing (vs undef). One of those undef != non-exist - because undef is a 
value in itself, and in this case the values simply don't exist to test.
