Bug#542686: libcompress-zlib-perl: uninstallable with Perl 5.10.1, needs to be removed

[Niko Tyni]

Package: libcompress-zlib-perl
Version: 2.015-1
Severity: wishlist

Perl 5.10.1 RC2 bundles Compress::Zlib 2.020 as part of IO-Compress.

This means that the separate libcompress-zlib-perl package will become
uninstallable when perl 5.10.1 enters sid.

The uninstallability will also break versioned reverse dependencies:
 filterproxy
 libimage-size-perl
 libpar-packer-perl
 mailscanner
because versioned dependencies are not satisfied by provided packages.

It seems clear to me that this package has to be removed, possibly in
favour of libio-compress-perl if we want to keep that as a separate
package (see #538214).

So the packages listed above need to be changed. All of these versioned
dependencies would be satisfied by Perl 5.10.0 already, so they should
instead be something like

 Depends: perl (>= 5.10) | libcompress-zlib-perl (>= X)

which allows for libcompress-zlib-perl removal but keeps any Etch
backporters happy.

I'll clone and reassign the four bugs and mark them as blocking this
one. Setting the severity to 'wishlist' for now, but it's definitely
going to upgraded later.
