to follow up on that - one elephant trap in the w32<=>unix conversion is first line:

#!/usr/bin/perl
[download]

If you've written that with a windows editor that line will probably be:

#!/usr/bin/perl<carriage return>
[download]

so the system looks for the file "/usr/bin/perl".chr(13) and doesn't find it. If you're ftping the files make sure you transferred the scripts as ascii files. Run a  tr -d \\015 <filename.bad > filename.good for good measure
