in reply to -T t t t t t o o late folks

Let me guess: the webserver is IIS (or any other than apache)?

If I remember correctly, IIS and some others don't read the shebang-line in the way Apache does. So you have to tell IIS to call Perl with -T within the configuration of IIS.
Beware - if there are scripts on that server that haven't been designed for use with -T, they are likely to break.
