This was a way to avoid breaking the huge number of perl scripts that
had: #!/usr/bin/perl as the first line. If perl simply moved to
/usr/local/bin, this would have broken a LOT of stuff people were doing,
so it was decided to put a link in /usr/bin. The port now has an option
to control this, but it is still there by default:
