It just seems weird to me, regardless of what sys.path is, that
os.system('/path/to/command/command')
would run a different version of 'command' than what is specified.
I'm not sure I can easily give steps to reproduce exactly what I'm
doing, but you could try running any python script you like in the
above way (in the Sage notebook) and see which python is used (perhaps
by using something you only have installed in the framework).
Its not worth my time to try to get Sage to compile a framework
version. Actually, all I want to do is manipulate an image for a
linear algebra class. There are some open tickets that try to improve
image importing in Sage (without the PIL) but I think progress on them
has stalled.

not the one in the explicit path I gave. Why is this happening and
how do I work around it?
When fooling around with system python vs sage python, I've made
mileage by manipulating sys.path... when Sage starts up, it sets
sys.path to a very different value to what system python uses.
Can you give steps to reproduce? (How are you running system python
from sage's python?)
And... ahem... this may not be the best place to mention it, but if
you're up for some pain, you can configure sage such that python is
compiled as an OS X framework. You then hopefully wouldn't need the
system python from within Sage's python kludge.
