I was actually going to propose that, but I was afraid of throwing two
bombs in the same day. :)

OS X will need to get Python 3 from Homebrew sooner or later anyway.

Trusty does have a python3.5 package, perhaps you could ask the
maintainers to install it.

CentOS 7 doesn't have "native" Python 3 (even the 3.4 version you have
there is probably coming from Fedora) but it has software collections,
where you have to do "scl enable rh-python35 './configure && make'".
You can check if scl and the rh-python35 software collections are
already installed.
