Compilation failure due to msgpack incompatibility

[Stickerpants]

I notice that #272 was merged, but I still got the same msgpack compilation error when I tried to install via homebrew. Output is pasted below - has the fix just not been fully deployed yet, or are there more issues?

272 was merged. However, it doesn't seem that @rogual did a new release. It should build when getting the latest. This can be done by running the following command:

brew install --HEAD neovim-dot-app

I see, that makes sense. Thank you for the update! I have no further questions on this, so I'll close it now.

Ran into this issue today as well, @bambu's answer fixed this for me, but perhaps the brew release could be updated @rogual?
