build updated Ubuntu packages daily based on repo status
Since pandas is developing very quickly, daily packages can help users to keep track of changes while using their usual software install mechanisms.

Launchpad offers inidvidual package repositories (PPA) and automatic build procedures based on the [bazaar repository](https://code.launchpad.net/+branch/~pythonxy/numpy/pandas), a mirror of the github repository.

As part of the [PythonXY for Ubuntu initiative](https://launchpad.net/~pythonxy), a bzr builder [recipe has been set up](https://code.launchpad.net/~timmie/+recipe/pandas-daily-current) to automatically create updated packages after repository changes.

The packages will be placed in the [Packaged Upstream Development Snapshots](https://code.launchpad.net/~pythonxy/+archive/individual-devel).

This bug shall track problems encountered during the builds.
