+Based on debian patch:

+Author: Barry Warsaw <barry@debian.org>
+Patch-Name: pth-installation-path
+Subject: Calculate the correct .pth path
+
+ cov-core wants to install the file init_cov_core.pth so that cov_core_init
+ will be imported and initialized automatically for subprocess coverage, if
+ the environment variable COV_CORE_SOURCE is set (which e.g. nose does
+ automatically).  However the upstream setup.py tries to install this file
+ directly into /usr/lib/pythonX.Y/{site,dist}-packages, which clearly doesn't
+ work when building the package.  This patch hard codes the .pth path for a
+ location within the build directory.  dh_python{2,3} does the rest.
