distutils package installation isn't compatible with IronPython.
To reproduce first install IronPython 2.6 (RC1 is currently latest version) from the msi installer. This installs by default on Windows into "C:\Program Files\IronPython 2.6" and includes a "site-packages" folder in the "Lib" subfolder.
With the simplest Python package created with "python setup.py sdist" (CPython) from the first example in the distutils documentation I get the following on install:
C:\compile\test\foo-1.0>"C:\Program Files\IronPython 2.6\ipy.exe" setup.py install running install running build running build_py creating build creating build\lib copying foo.py -> build\lib running install_lib copying build\lib\foo.py -> C:\Program Files\IronPython 2.6\Lib\site-packages error: C:\Program Files\IronPython 2.6\Lib\site-packages\foo.py: None
C:\compile\test\foo-1.0>dir "C:\Program Files\IronPython 2.6\Lib\site-packages"
Volume in drive C has no label. Volume Serial Number is FC33-85DD
Directory of C:\Program Files\IronPython 2.6\Lib\site-packages

See also the following bug report against IronPython on the codeplex issue tracker. Here the distutils install fails in bytecode compilation.
http://ironpython.codeplex.com/WorkItem/View.aspx?WorkItemId=24810
Bytecode compilation should not be attempted on IronPython as it does not use Python bytecode. ( sys.dont_write_bytecode is True )
The fixes should be backported to Python 2.6 if possible as IronPython 2.6 uses the standard library from SVN and will pick up changes even between releases.

Hmmm... ok, so I was running on Vista where a normal user can't create files in the "Program Files" directory anyway. If I run with elevated permissions then I get the same error as reported on the IronPython issue on codeplex (which is probably what you will see if you try this on Windows XP):

So there are two issues here - the terrible error message when an install fails with an access denied error and the fact that distutils attempts to compile bytecode under IronPython.

Notice that install_lib has a --no-compile option that can be used to avoid compiling .pyc/.pyo files.
What I am adding now is just a gentle warning in case a compilation is tried and sys.dont_write_bytecode is True, so the installation may proceed nevertheless and it doesn't through an error.
For the 2.6 backport, it can be added in 2.6.5 I guess,

Done in trunk (r75669, and r75670 and r75671) and Py3k (r75704) and 3.1 (r75705).
I'll push in 2.6 when the branch is unfrozen.
Michael, could you create another issue for the access rights problems ? It'll be easier to track.
Thanks!

This problem showed up when installing a package with IronPython, where the site-packages folder requires admin privileges to write to (which should be true with CPython Windows but isn't).
If you perform a 'python setup.py install' without admin privileges the install fails (as it should) but with a very cryptic error message:
C:\compile\test\foo-1.0>"C:\Program Files\IronPython 2.6\ipy.exe" setup.py install running install running build running build_py creating build creating build\lib copying foo.py -> build\lib running install_lib copying build\lib\foo.py -> C:\Program Files\IronPython 2.6\Lib\site-packages error: C:\Program Files\IronPython 2.6\Lib\site-packages\foo.py: None

Sorry - meant to create a new issue.

I think this change was wrong. Please see my rationale in http://bugs.python.org/issue12119.
(BTW, I’d be surprised if byte compilation was the only compat issue with distutils and IronPython. For a start, sys.version[:3] is used to get the version number. I should be able to get Mono and IronPython in a few weeks or months and see how much issues there are in distutils and distutils2.)
