If I'm following correctly, all you need to do is wrap the require call in an eval. If it is successful, the code loaded and can be used. If it's not, I don't think any of the code can have loaded (a more perlgutsy monk will correct me if that's wrong) and you'll get the error in $@. This snippet might help you get started: 

perl -le 'eval { require(shift) }; print $@ ? "ERROR: $@" : "Loaded fi
+ne!"' /home/path/to/upgrade/files/my_code.conf
ERROR: Can't locate /home/path/to/upgrade/files/my_code.conf in @INC (
