So I've finally convinced packages to build from master again. At the
moment, the only patch required that's not already in master is the one
on bug 8636, and that's just because I had to make a change to it today.

You can find these in the squeeze-dev repo.

Additionally, and of particular interest to koha-devel is the addition
of two new packages: koha-deps and koha-perldeps. 

Koha-deps depends on things like apache and mysql-client, but not the
perl modules. Koha-perldeps is similar, but it only contains the
perl-related dependencies. Put these two together and it's like having a
full koha-common install, but without koha itself ending up on your
disk.

This'll hopefully make setting up developer environments a little
easier. Thanks to Sofiane El harsal at Biblibre for this.
