"$FRED" only gets expanded if it is in Perl code. It sounds like you have that in data. So post-process your data with: 

s/\$([A-Z0-9_]+)/$ENV{$1}/g for $myhash{$mykey}, ...;

(which doesn't require "use Env;" which is something that I would never use -- it sounds rather dangerous in some situations, allowing people to throw in variables not in your control and just to save you from typing 'ENV{' and '}'.)
