Reduce package/library duplication in lucid

Registered by Martin Pitt

Lucid has a lot of duplicated library and package versions. For improving supportability, reducing CD sizes/memory overhead, and avoiding library conflicts we should clean those up and build packages against the latest available versions.

pitti, 2010-03-08: I checked lucid main for duplicate versions and added them to the wiki page. There is certainly some stuff that we can ignore (like multiple build-time tools versions, especially if they would only lead to introducing a delta to Debian), but some libraries seem quite important. Initial proposed set of work items created.
Open question is whether we want to attempt to get rid of tcl/tk 8.4?

LSB 4.0 (the one that we currently use) requires Qt3 (as well as Qt4), so we can't drop that yet.

libgdata and the libgdata1.2 from evolution are two totally different APIs, so nothing to migrate there.

doko, 2010-03-15:
 - python2.6 & db4.8: backported and tested, upload after beta1

doko, 2010-03-09:
 - db4.7: major blocker is python2.6; besides changing the configure check, this needs checking for regressions when
+building with db4.8
 - autoconf2.59/gcc: WONTFIX; this package was explicitly introduced for gcc-4.4, and either would require pregenerating all configure file with 2.60, or updating gcc-4.4 to use a newer autoconf which is a major pain.

Would deprecation of libglade in favor of gtkbuilder fit into this spec?
I haven't done any rdepends, but I suspect there is a lot of code still using libglade, even though it is being deprecated (

pitti, 2010-03-10: This doesn't cover things like glade vs. GtkBuilder, since these are two different APIs (they are just duplicates in a "purpose" sense). This particular topic was discussed in a different blueprint:

pitti, 2010-03-30: Migrated most stuff to db4.8. I tried sendmail, but it uses on-disk transactions and needs proper migration code in postinst. Since the sendmail binaries are in universe, and this will require a nontrivial amount of work and testing, I drop this for lucid. Remaining one is openldap.

ziesemer, 2010-04-30: Why was openldap dropped for db4.8? Anything I can help with? (I'd like to have this for my own system, without having to re-patch everytime there is an update.) Edit: Created bug:
