First off, I see no reason why this shouldn't be possible, since Sage just uses 
python anyway. Let me tell you what I'm doing and the error that I get:

I reference the same exact Python version that Sage uses from the 
sage/local/lib directory.

I tell python to pretend it's argv consists of a string with the full path to 
the sage binary in /local/bin.

I set the python home directory to /local.

Here's the error I get:
dlopen(/Library/WebServer/mod_sage/sage-6.1.1/local/lib/python2.7/lib-dynload/operator.so,
 2): Symbol not found: __PyUnicodeUCS4_AsDefaultEncodedString Referenced from: 
/Library/WebServer/mod_sage/sage-6.1.1/local/lib/python2.7/lib-dynload/operator.so
 Expected in: flat namespace in 
/Library/WebServer/mod_sage/sage-6.1.1/local/lib/python2.7/lib-dynload/operator.so

Can you guys tell me what I'm doing wrong?

Just to clarify: are you running Sage's python, or trying to run a different python than the one compiled in Sage? If you want to run python and import the sage library, you might consider doing:

sage -python myscript.py

Googling for PyUnicodeUCS4_AsDefaultEncodedString indicates that the error shows up when python is compiled with different settings for the --enable-unicode compile switch, for example, https://www.rosettacommons.org/node/1901

Thanks,

Jason
