=item __inet_* errors

If you receive unresolved symbol errors during Perl build and/or test
referring to __inet_* symbols, check to see whether BIND 8.1 is
installed.  It installs a /usr/local/include/arpa/inet.h that refers to
these symbols.  Versions of BIND later than 8.1 do not install inet.h
in that location and avoid the errors.  You should probably update to a
newer version of BIND (and remove the files the old one left behind).
If you can't, you can either link with the updated resolver library provided
with BIND 8.1 or rename /usr/local/bin/arpa/inet.h during the Perl build and
test process to avoid the problem.
