The first time I built a Python 3, I didn't know about 'make
altinstall', and managed to make something of a mess of my system (the
default Python is 2.6.6 on Ubuntu, IIRC, and there are system scripts
that don't work on Py3). But now, it's pretty easy, as yesterday can
attest: I did a fresh install of Debian, starting at about 11AM, and
by mid-afternoon everything was built and deployed. Most of that time
was spent cloning about 8-10 source repositories (including one local
one of "work stuff") and building stuff from source, and not one of
the programs gave me any trouble. Python 3 was among them.

Now, granted, this was Debian and I can't speak for Centos. But it
would surprise me greatly if your package manager can't provide build
