This was fixed in Log4perl 1.35:

I wouldn't do it in the main root to avoid stepping on the package
manager's files, but if you maintain your own local directory via
local::lib that should work just fine. Ideally, I wouldn't use the
system perl for applications in the first place, but install a separate
one via perlbrew et al.

Later versions of Debian seem to have more up-to-date versions of
Log4perl:
