libperl5.10 5.10.0-22ubuntu1 (lpia binary) in ubuntu karmic

 This package is required by programs which embed a Perl interpreter to
 ensure that the correct version of `perl-base' is installed. It
 additionally contains the shared Perl library on architectures where the
 perl binary is linked to libperl.a (currently only i386, for performance
 reasons). In other cases the actual library is in the `perl-base' package.
