I am trying to update the Gentoo package for scikits_learn (different name, but it refers to this package).

This is the build.log.

I presume the issue is:

E               urllib.error.URLError: <urlopen error [Errno -3] Temporary failure in name resolution>

This would be because Gentoo sandboxes the installation, in order to avoid security issues resulting from packages dynamically downloading data the identitiy of which is not guaranteed by matching a checksum recorded by the package manager. So it's not surprising, and potentially an easy fix.

1. Is this the only issue here?
2. If so do you have a test data archive which I can download via the package manager? (i.e. via wget)
