If augeas is not installed, you get a return message:
{'kermit': 'No module named augeas'}
(here on minion kermit).
I think it is better to handle this with module checks and error messages than to force harsh dependencies for func.
Anyway I'm working on 2 other modules doing conf. management and using more classical modules (re and ConfigParser), as an alternative.

Just as a general question, how is Func going to handle the dependency
of modules?
Is every module going to have all the dependencies added to the main
Func package, should sub-packages be created, or ....?
I'd be in favour of having "main/supported" modules which are
supported everywhere then creating subpackages for everything else (I
would be willing to do this work).
The augeas module would probably be good to have everywhere, but I can
see other modules causing issues.
I'd expect any module included with the main Func package to have all
its dependencies meet, but forcing everyone to include tons
dependencies, especially when older distros are supported, is going
cause massive pains for systems administrators (ex: augeas being a
newer project probably doesn't have a package in EPEL 3,4).
