Andrew, try to read `perldoc perlrun`

Near the 60-th line several shamanic tricks are suggested to execute a Perl
script if it is not known a priori where the executable is located:

           #!/bin/sh
           #! -*-perl-*-
           eval 'exec perl -x -wS $0 ${1+"$@"}'
               if 0;

or

           #!/usr/bin/env perl

Of course, the second will not work if NetBSD has no /usr/bin/env, and the
first if `sh' under NetBSD is not in /bin.

Although I personally would prefer a recommendation to either manually
symlink /usr/pkg/bin/perl to /usr/bin on such systems, or manually edit
shebang in all the *.pl scripts (ContextManual.pl as well) when building
CinGG under exotic OS. I am afraid of too shamanic techniques.

I inserted -ldl just because `man dlopen` instructs to do it. May be, it can
work without it (for example, if some other shared library linked to plugins
by default requires it already), I just did not test.
