I've installed IPython 0.5.0 with `python setup.py install'
then:
---
[18:46] $ipython
Python 2.3.3 (#1, Dec 22 2003, 11:56:28)
Type "copyright", "credits" or "license" for more information.

IPython 0.5.0 -- An enhanced Interactive Python.
?       -> Introduction to IPython's features.
@magic  -> Information about IPython's 'magic' @ functions.
help    -> Python's own help system.
object? -> Details about 'object'. ?object also works, ?? prints more.

In [1]: import os

In [2]: xmode verbose
Exception reporting mode: Verbose

Maybe upgrade your cygwin? My dll version is 1.5.7-1
(run `cygcheck -s | egrep "^cygwin"' to find your version)

HTH.
