If the output from your program is all that you have, then no, you can't rebuild, as all the reference tells you where perl was storing the value that you cared about.

If you have the program that generated that file, and all of the input that it took, then you may be able to modify it, and re-run it, so that it generates the output you are looking for. If that's the case, I'd suggest that you post the program that generated the output.
