I can't help wondering how you got Encode to install.

This is what you'd see when you tried perl Makefile.PL when you tried  
to do so.

% ~/perl562/bin/perl Makefile.PL
Perl v5.7.3 required--this is only v5.6.2, stopped at Makefile.PL  
line 1.
BEGIN failed--compilation aborted at Makefile.PL line 1.

0th of all, Encode requires Perl 5.8 and above (Perl 5.7.3 to be more  
exact but it's a developer version).  I have no idea what you use  
Encode.  All I know is I cannot support your case.
