Installing Net::SFTP

I am trying to install Net::SFTP and the install SEEMS to have  
worked. However, when I try to open a new connection I get the  
following errors:

Key class 'Net::SSH::Perl::Key::DSA' is unsupported: MIME::Base64  
object version 3.05 does not match bootstrap parameter 3.07 at / 
System/Library/Perl/5.8.6/darwin-thread-multi-2level/XSLoader.pm line  
92.
Compilation failed in require at /Library/Perl/5.8.6/Net/SSH/Perl/Key/ 
DSA.pm line 13.
BEGIN failed--compilation aborted at /Library/Perl/5.8.6/Net/SSH/Perl/ 
Key/DSA.pm line 13.
Compilation failed in require at (eval 32) line 1.
BEGIN failed--compilation aborted at (eval 32) line 1.

Did the install not tell me about a needed prereq or did the install  
actually fail for some reason. I am pretty much at a loss as to what  
to do. Thanks.
