vdsm fails again becasue cpopen is not found

[Nir Soffer]

Hi infra,

checking python module: cpopen... no
configure: error: failed to find required module cpopen
Build step 'Execute shell' marked build as failure
Build step 'Groovy Postbuild' marked build as failure
Recording test results
Finished: FAILURE

See http://jenkins.ovirt.org/job/vdsm_unit_tests_gerrit/6425/console

Any idea why it broke again?
