How to set env variable? I'm using PERL in WINDOWS.

In your code you can specify the directory location of the pm:
use lib '/path/to/pm';
That makes no sense. It would cause Perl to look for
/path/to/pm/XML/Handler/YAWriter.pm
and the module would not be found.

eval { $ssh2-connect($_) };
if ($@) {
warn Unable to connect host $_: $@ and next;

#...@export_ok would be better
In this case there is only one package. Would you still bother with
Exporter? Why?
