[San-Diego-pm] Shebang path issue

It's not that Perl on Windows ignores the #! line, it's that Windows
doesn't use it. It's a Linux thing (by which I mean *nix, but most
people use Linux these days). The program loader uses it to find the
interpreter to use. Windows instead uses registry entries to associate
file extensions with programs.

In any case, running 'perl script.pl' in either Linux or Windows will
use whatever 'perl' shows up first in the path.

Apache on Windows will use the #! line to find the interpreter, since
it doesn't have any other way of doing so. I assume, then, that you've
installed Perl on Windows under 'C:\perl'.

If that works, what workaround are you looking for?
