Problem with regression tests in cloud-init 0.7.4.

[Charles Plessy <plessy@debian.org>]

Dear all,

I would like to update cloud-init to version 0.7.4, but it fails to build from
source in a clean schroot with errors such as the following.

	dh_auto_test
	/usr/bin/make test
	make[2]: Entering directory `/«PKGBUILDDIR»'

Strangely, it built fine on my Destktop machine.  Perhaps a package is missing,
but the error message does not suggest which one.

Does anybody has an idea ?
