Sorry, as I just wrote in bugzilla we didn't know about your bug.
1) I am not copied on the bugs because I don't own the overlay
2) Christopher is, but bugzilla has his old email address,
effectively he probably never received it.
3) The overlay, more or less target people on `arch` rather than
`~arch`. I am expecting users in `~arch` to know what they are doing
to some extent and be able to deal with blockers.

That being said you raise the problem of numpy 1.8 which I could address
independently of upstream so I will but I cannot give you a time frame.
