Comment 1 for bug 1004000

I did some more experiments:

If I restrict the version in setup.py to

'zope.component<3.11'

I get the next error message:

While:
  Installing interpreter.
Error: There is a version conflict.
We already have: zope.interface 3.5.1
but zope.schema 4.2.0 requires 'zope.interface>=3.6.0'.

If I instead restrict the version in setup.py to

'zope.interface>=3.6.0'

I get another error message:

While:
  Installing test.
Error: There is a version conflict.
We already have: zope.interface 3.5.1
but mailman 3.0.0b1 requires 'zope.interface>=3.6.0'.

BTW this error also happens with mailman 3.0.0a8 on the same machine...
