Hi,
IPython should use the Python interpreter in the current environment and
not hardcode /usr/bin/python.
The rationale is that IPython as packaged right now is unusable inside a
customised environment like those created by virtualenv.

I would expect IPython to behave like python:

IPython uses the global Python interpreter whereas python uses the one
from the currently configured one, which means that the current environment
is missing in sys.path.
I did *not* specify '--no-site-packages' in the virtualenv call, because
i would have to install IPython in the newly created environment which
will solve the here described problem as well.
This can be easily fixed by replacing #!/usr/bin/python with
#!/usr/bin/env python .
