Under Windows 2K:
sys.platform = win32
os.name = nt

Under Cygwin:
sys.platform = cygwin
os.name = posix

I just tried setting IPYTHONDIR before running setup.  This time the
setup completed successfully!  Of course, it would have been more 
convenient if the installer had recognized that $HOME was set.

One remaining problem with the Cygwin install is that it creates the 
.ipython/*rc files with .ini extensions but when ipython runs it looks 
for rc files without extensions, so you have to rename them.

Hope this helps.
