This error is a bummer. It comes from innoDB implementations of SQL servers.
The main idea is that there is a limited length for the index deployment on
varchar fields, and one field in django-allauth/mailman is 255 chars, which
is more than 767 bytes (191 chars).
What SQL server do you use?
Regarding the missing dependency, we'll add it as soon as possible. :)

It's far easier to fight for one's principles than to live up to them.
