Yeah, Ubuntu is a bit of a mess when it comes to pandas and the things 
it depends on.  Apt gets you numpy 1.4.1, which is really old.  Pandas 
won't even install on top of it.

I've got pandas (and numpy, and scipy, and matplotlib) running on a 
Ubuntu 12.04 box.  I installed everything with pip.  My problem at this 
point, however, is I want to replicate that setup in EMR (Amazon's 
Elastic Map-Reduce).  In theory, I could just run "pip install numpy" in 
my mrjob.conf bootstrap, but it's a really long install process, 
building a lot of stuff from source.  Not the kind of thing you want to 
put in a bootstrap for an ephemeral instance.

Does anybody know where I can find a debian package for numpy 1.6?
