I also noticed that you have the use lib as:
> use lib ("/perl/lib/Net");

but then you say this

> use Net::FTP;
since you are defining the root lib directory as Net, it might be that you can't include it correctly. It is probably looking for Net::Net::Ftp.

maybe change your use lib to:

> use lib ("/perl/lib");
or
> use lib ("C:\perl\lib");
since you are using win
