Django/Apache/mod_wsgi not using virtualenv's Python binary
I had the same situation in a Pylons app and ended up using /usr/bin binary plus virtualenv site-packages dir instead.
Of course it was the same python version...
I have a virtualenv at /opt/webapps/ff/ with its own Python installation.  I have WSGIPythonHome set to /opt/webapps/ff in my Apache config file (and this is definitely getting used in some capacity, because if I set it to a slightly different existing directory and restart Apache I get a 504).  But if I e.g. assert False in a view somewhere to bring up the Django debug page, I see that settings.PYTHON_BIN is /usr/bin rather than /opt/webapps/ff/bin.
How do I get Apache/mod_wsgi to use my virtual environment's Python binary?  I thought setting WSGIPythonHome was the way to do this, but it only seems to affect which site-packages dir is used, not which binary is used.  Thanks.
