Is the newrelic module installed into a Python virtual environment or into a 
real Python installation?

That it is not found suggests a few possibilities.

1. The mod_wsgi is compiled against a different Python version.
2. You have a distinct Python 2.7 installation (system wide one) which is 
different to the one you are expecting it to use, and mod_wsgi is compiled 
against or using the other installation.
3. You are using a virtual environment but haven't told mod_wsgi how to use it.

I would suggest going through the following checklist.

1. Work out what version of mod_wsgi is compiled against. First up by looking 
at what libpythonX.Y.so it is using.

2. Work out what Python installation, version and location, mod_wsgi is using 
at run time.

3. Also validate whether mod_wsgi is running your application in embedded or 
daemon mode and whether that is what you expect.

http://code.google.com/p/modwsgi/wiki/CheckingYourInstallation#Embedded_Or_Daemon_Mode
http://code.google.com/p/modwsgi/wiki/CheckingYourInstallation#Sub_Interpreter_Being_Used

Supply the results of that as well as what you have for the WSGI directives in 
your Apache configuration.
