it looks like something changes in how some vars (ie buildout:egg-directory) gets computed between 1.0.2 and 1.1.0

is the resulting error for:

eggs-directory = ${buildout:directory}/develop-eggs

instead of:

'/Users/whit/dev/geo/alm3/develop-eggs'

(which I believe works until at least 1.0.2)

OSError: [Errno 2] No such file or directory: '/Users/whit/dev/geo/alm3//Users/whit/dev/geo/alm3/develop-eggs' buildout seems to implicitly assume I want buildout:directory appended. is this a feature, bug, or something I can turn off?

The way buildout normalizes buildout paths did change in 1.1.0. I haven't seen this error and can't see, in the code, while this error would occur.

Can you provide a buildout I can use to reproduce this problem?

I saw this problem which broke minitage too a week ago.

Jim, you can see all the buildouts in there : http://trac.minitage.org/trac/browser like:http://trac.minitage.org/trac/browser/minitage/buildouts/dependencies/bzip2-1.0.4/buildout.cfg.

They will all fail with zc.buildout >= 1.1

Not for me. :)  I've tried on both Ubuntu and Mac OS X.

But I've been able to create another buildout that seems to exhibit the same symptom.

You may have tested the fixed buildout ;) . see:
http://hg.minitage.org/hg/minitage/buildouts/dependencies/bzip2-1.0.4/file/2e3ea95738e5/buildout.cfg


The problem is not the join(), but with variables substition.

I may be wrong but it s how i understand things happen:

The sample buildout snippet:
    [project]
    foo = /abspath/a
    [buildout]
    eggs = ${project:foo}

Then we run buildout:
li.135
    No substitution there, we use data.
    >>> os.path.join(
        '/abs/path/to/buildout/',
        '${project:foo}')
    '/abs/path/to/buildout/${project:foo}'

li.172
    Substitution there, we use self['buildout']:
    # '/abs/path/to/buildout/${project:foo}' -> 
'/abs/path/to/buildout//abspath/a'
    >>> options['eggs'+'-directory']
        '/abs/path/to/buildout//abspath/a'
    >>> os.path.join(
            '/abs/path/to/buildout/',
            '/abs/path/to/buildout//abspath/a')
    '/abs/path/to/buildout//abspath/a'

By prefixing, yes i meaned to prepend the buildout path to the variables in buildout part but i might not been enought clear.
