Actually, waf configure --disable-python just disables the python
_bindings_ for ns-3.  All the python scripts for tests and such will still
work without python bindings, since they interface with ns-3 via subprocess
spawning.

But, I agree with you that it would be best to make python bindings
buildable in CentOS.
