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.
