[gentoo-user] python 2.x vs 3.x

[Mark Knecht]

In a current thread started by Meino where he is having trouble
emerging hydrogen he reported the following quoted data to Neil. I
don't believe Neil has responded yet but Meino's data brought me back
to a question I've meant to ask for a while so I'll take this
opportunity.

From Meino:

<QUOTE>
With

   eselect python list

I get

Available Python interpreters:
 [1]   python2.6
 [2]   python2.7
 [3]   python3.1
 [4]   python3.2 *
</QUOTE>

which shows python3.2 as the system wide default.

   It's been my understanding ever since we first emerged any
python-3.x version that we were not supposed to set any version of
python3 as the system wide default. On all of my systems I have
something like this:

c2stable ~ # eselect python list
Available Python interpreters:
  [1]   python2.7 *
  [2]   python3.2
c2stable ~ # eselect python list --python2
Available Python 2 interpreters:
  [1]   python2.7 *
c2stable ~ # eselect python list --python3
Available Python 3 interpreters:
  [1]   python3.2 *
c2stable ~ #

   Now, like Paul Hartman I didn't have any trouble building and
running Hydrogen as a Jack client. It works just fine for me. However
no one else seemed to have picked up on Meino's configuration which
makes me wonder if I missed the memo to make the 3.x version of the
system wide default.

   What is the current best practice in this area?

Cheers,
Mark
