I don't really understand what you are trying to do, but I would advise
to use environment variables to control the behaviour of the fake scripts
in /usr/local/bin
In bash you can do
export PYVERSION=2.5
And from that time onwards everything defaults to python2.5.
note the ${PYVERSION} that I have included now in the sample scripts
below to select the python version.
I don't think you need to, but if you want to change the environment
variable inside python you can set environment variables with something like
os.environ.????? Look at the docs.
Caveat1: I have not tested this, but it should work ok. The setup I use is
much simpler: just default to python2.7
Caveat2: Arch linux packagers dont use a consistent naming of things:
There exists /usr/bin/virtualenv3, but there does not exist
/usr/bin/sphinx-build3 (it is /usr/bin/sphinx-build)
Somebody should send a bug to the package maintainer.
PS: Once you setup a workaround to bypass all the python=python3 nonsense,
Arch Linux is a nice linux distro, the best out there. I will stick
to it.
