Set environment variables for virtualenv & pip modules to use custom python interpreter

[Vye]

Is there a way to modify environment variables such as PATH and
LD_LIBRARY_PATH for modules pip and virtualenv? I believe the
functionality I'm looking for is supplied by modules.environ but I'm
using 2014.1 which it is not included in.

I want to create a virtualenv from an optional Python installed in
/opt/rh/python27 (RHEL).

/srv/www/app/venv:
virtualenv.managed:
- python: PATH=/opt/rh/python27/root/usr/bin${PATH:+:${PATH}}
LD_LIBRARY_PATH=/opt/rh/python27/root/usr/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
python2.7
- use_wheel: True
- requirements: /srv/www/app/requirements.txt

produces the following error:
ID: /srv/www/app/venv
Function: virtualenv.managed
Result: False
Comment: An exception occurred in this state: Traceback (most

python2.7) does not appear executable.

I could avoid setting PATH by using the absolute path but
LD_LIBRARY_PATH still needs to be set so Python can find the
libraries. What's the best way to accomplish this?

You could try syncing `salt/modules/environ.py` to your minions as a custom module by taking it from the develop branch and sticking it in the `/srv/salt/_modules` and running `salt '*' saltutil.sync_all`.  That doesn't always work if it relies on utils that are not available in the version of salt that you're using, but it's worth a shot.  Otherwise, I'm not really sure how to set these variables for the salt process.
