Bugzilla Bug 134953

app-arch/rpm-4.2 doesn't compile when having the python USE-flag set.
I know it's a ~x86 Portage I use, but I think this doesn't matter here.
I've already tried to disable distcc and ccache, but this didn't solve the
problem.
After disabling the python USE-flag, app-arch/rpm-4.2 emerged without errors.
