in reply to set env var at compile time

I'm guessing here but I think you have to satisfy ld.so and it reads from the process's C environment which is not updated by updating the perl variable %ENV. I see no problem with having a configuration file somewhere on disk but you'll need to write it in bash (or similar) and just make sure that invoking it is a part of your /etc/profile or how you invoke perl.

    Satisying ld.so makes sense, as does the failure of %ENV to update its environment. I wished for a Perl solution, but I suppose a shell script is better than hard coding the path. It's not really any better than just adding the 'env' to the crontab line, though, so I'll probably just hold my nose and go with that. Thanks for taking the time to respond.
