perl-modules 5.10.1-17ubuntu4 (i386 binary) in ubuntu natty

 Architecture independent Perl modules. These modules are part of Perl and
 required if the `perl' package is installed.
 .
 Note that this package only exists to save archive space and should be
 considered an internal implementation detail of the `perl' package.
 Other packages should not depend on `perl-modules' directly, they
 should use `perl' (which depends on `perl-modules') instead.
