Maybe I'm misunderstanding you, but it should be simple. If you have the 
base Perl class 'Base' that wraps methods in the C++ base class 
'BaseCpp' (separate names for clarity), you can create the Perl class 
'Derived':

package Derived;
use strict; use warnings;
our @ISA = qw(Base);

1;

And write the XS to wrap the new methods in the derived C++ class 
'DerivedCpp' (and put those methods in the Perl Derived namespace). You 
probably need to wrap the derived class' constructor anew.

You may also want to have a look at ExtUtils::XSpp. C++ & XS seems so 
much simpler since I discovered it. The newest release also converts C++ 
exceptions to Perl exceptions in a flexible way.

Best regards,
Steffen
