That's a bit difficult as I don't have shell access,
but one of our friendly sysadmins provided it, see
http://paste.pound-python.org/show/W7zyZNUTtfDAn8RAwi26/

For the full build logs when the test suite failed, see

for i586 build and
http://pkgsubmit.mageia.org/uploads/failure/cauldron/core/release/20160224202627.doktor5000.duvel.10775/log/botcmd.1456345627.ecosse.log
for the x86_64 build.
