I agree. That's why a redirector makes more sense, because
the redirector can be part of the base-system, and the port
can be installed in /usr/local.

Many many perl scripts already exist which do not do this.
Yes, we now know that it would be more portable to write
a script that way, but that doesn't magically change all
the scripts which are already written and which are very
used to assuming that perl is at /usr/bin/perl.
Also, the /usr/bin/env approach means that scripts are
now subject to the setting of $PATH, and that is not
necessarily a good thing. Remember that the person
running the script is not necessarily the person who
wrote it, and is not necessarily aware that it even
is a perl script, or that PATH is important when
running that script. (PATH would not be important
for a script which is using /usr/bin/perl)
