should include expected dependancies

[dwright]

Binary package hint: libio-compress-base-perl

issue:
libio-compress-base-perl does not include the necessary dependencies to produce desired behavior.

for example:
I would expect installation of this module, libio-compress-base-perl, to execute this code correctly for a compressed bzip2 file.

use IO::Uncompress::AnyUncompress qw(anyuncompress $AnyUncompressError) ;

my $status = anyuncompress $input => $output
              or die "anyuncompress failed: $AnyUncompressError\n";

however, since libio-compress-bzip2-perl is not installed the code 'fails' silently, i.e. it does not actually uncompress the file. (and does not report an error, which would be an upstream bug, except I believe this situation is not reached often, since IO-Compress has a dependency of 'Compress::Raw::Bzip2' and 'Compress::Raw::Zlib' in it's Makefile.PL)

$ lsb_release -rd
Description: Ubuntu 9.04
Release: 9.04

$ apt-cache policy libio-compress-base-perl
libio-compress-base-perl:
  Installed: 2.015-1
  Candidate: 2.015-1
  Version table:
 *** 2.015-1 0
        500 http://us.archive.ubuntu.com jaunty/main Packages
        100 /var/lib/dpkg/status

what was expected:
installation of this module should make the following code work as expected, for a bz2 file.
(i.e. $input is a bz2 file, $output is the uncompressed file)

use IO::Uncompress::AnyUncompress qw(anyuncompress $AnyUncompressError) ;

my $status = anyuncompress $input => $output
              or die "anyuncompress failed: $AnyUncompressError\n";

in order to make this code work I had to install, sudo apt-get install libio-compress-bzip2-perl

to reproduce:
a standard install of 'jaunty'

Please note that libio-compress-base-perl is superseded by
libio-compress-perl (apparently only in karmic at the moment) which
also produces a libio-compress-base-perl transitional dummy package.

libio-compress-perl also includes IO-Compress-Bzip2.
