You're very probably stuck.  Whilst you can use a hex editor to change
strings in the binary, you can't expand the length of those strings,
only contract them or retain the same length.

However, a solution would be to change the perl binary to use /opt/lib
instead of /usr/lib and make /opt a symlink to /usr/local.

There's a couple of reasonable hex editors out there, but I usually just
tend to use M-x hexl-find-file in emacs.  If you're a vim user, see
