Many Unixen have an arbitrary (ugh) limit of 32 chars on a #! line.

Alternatives are to install a symlink from someplace with a shorter
name to where it really is (installperl attempts to put one into /usr/bin),
or if that's administratively unlikely, put some other program on the
#! line that will start up perl for you:

    #!/bin/env perl

or some variant of

    #!/bin/sh --  # really perl

    eval 'exec perl -S $0 ${$1+"$@"}'
	if $running_under_some_shell;

But those both entail an extra process, which is a pity when #! is already
implemented.  Make the world a saner place and push for /usr/bin/perl.
