packages with a - (dash) talk too much

[Adam Groszer]

Packages with a - (dash) in their name that get translated to _ (underscore) talk too much.
Like:
    Develop: '/sample-buildout/sample'
    Couldn't find index page for 'wsgi_intercept' (maybe misspelled?)
    Installing var.
    Installing myapp.
    Generated script '/sample-buildout/bin/myapp'.
    Installing mydebug.
    Couldn't find index page for 'wsgi_intercept' (maybe misspelled?)
    Generated script '/sample-buildout/bin/mydebug'.
That breaks tests (of recipe packages).

What's again weird, because
...
    Getting required 'wsgi-intercept'
      required by zope.app.wsgi 3.9.2.
    Couldn't find index page for 'wsgi_intercept' (maybe misspelled?)
    There are no distros available that meet 'wsgi-intercept'.
    Using our best, None.
    Picked: wsgi-intercept = 0.4
...
where zope.app.wsgi 3.9.2 requires wsgi_intercept (with underscore).

More weird is that the PYPI page is http://pypi.python.org/pypi/wsgi_intercept/0.4
