it seems you are confused!

There are mainly two Perl modules implementing the SFTP protocol: Net::SFTP that 
runs on top of Net::SSH::Perl and Net::SFTP::Foreign that uses a binary SSH 
client to establish the SSH connection to the server.

Net::SFTP::Foreign::Compact is a thin adapter layer on top of Net::SFTP::Foreign 
implementing (most of) the API of Net::SFTP, so that programs written for this 
module can be easily be changed to use Net::SFTP::Foreign.

... well, actually, there is a third module implementing SFTP in Perl, 
Net::SSH2::SFTP, distributed as part of Net::SSH2, but it is not very powerful 
yet, lacking some indispensable features as "put" and "get" methods.
