Unless you are a user without root rights on a strange system without a standard perl installation, the best way is to use "#!/usr/bin/perl". In most of the cases (that is close to 100% on a sane modern POSIX system) there is a good perl binary installed at this location. And in rare cases when there is not or you need a different one, you may create a symlink or a shell wrapper /usr/bin/perl to call the correct perl executable depending on the current working directory or the user. Other solutions although may be fine for some specific project, can't be suggested in general, since they are either non-portable (call an executable unexisting on other systems) or unsecure (may do different things depending on the user PATH). One more shortcoming of the "/usr/bin/env perl" method is that you can't specify additional parameters to "perl", like "-w" or "-C0". At least on all systems I can find. So Wikipedia lies here in one of its examples.
