build and doc-open thwarted due to feature rename-dependency

[gbonnema]

I cloned the repo for the master branch and the compile returns an error as follows:

error: failed to parse manifest at `/home/data/gbonnema/projects/rust/mime/Cargo.toml`

Caused by:
  feature `rename-dependency` is required

this Cargo does not support nightly features, but if you
switch to nightly channel you can add
`cargo-features = ["rename-dependency"]` to enable this feature

I added the line cargo-features, but nothing changed. I fear, if I switch to nightly channel, this will affect other projects as well.
Is it possible to not have the rename-dependency? What else can I do to correct the situation?
