thank you every one for the above solutions, But in my case none of the above module was installed.Hence i found another way to do it.I am sharing the method i followed here just incase someone get in to my kind of situation
Download Net::SFTP::Foreign zip file ,unzip and copy the source code DIR to ur pwd .using 'use lib 'path to unzippeed file' and use Net::SFTP::Foreign ' will enable you to use the functionalities of Net::SFTP::Foreign module locally,no need to install it and it has no dependencies on external module
