Trying this now, using setuptools-0.6c6dev_r54241, but I must be doing
something wrong here, because I cannot get it to work.

What I do is:

   easy_install -f \
   https://user:secret@myhost.com/trac/wiki/PackageIndex SomePackage

This index page requires authentication and easy_install can indeed
read the index page with the supplied credentials. It finds the
correct download URL too, i.e.:

  https://myhost.com/svn/somepackage#egg=SomePackage

It was my understanding that easy_install would reuse the credentials
as specified for the index page URL, since both host and scheme are
identical for the download and index page URLs. However downloading
fails, with a 401 Authorization Required error.

As I said, it could very well be I'm doing something wrong here. Any
hint is highly appreciated.

kind regards,
jw
