Depend directly on enum34
enum-compat
is a virtual package bringing in enum34
when necessary, it is the same as depending directly on enum34
conditionally.
See upstream: https://github.com/jstasiak/enum-compat/blob/ae41cfa712e837596f7d26a5283be40ec5b84084/README.rst
Also, enum-compat
is not packaged by a lot of distributions, while enum34
is.
