These open issues may also help:
Build a proper release version of neovim, not a release with debugging info version https://github.com/neovim/homebrew-neovim/issues/209
Can't install via homebrew-neovim if luarocks path is set explicitly https://github.com/neovim/homebrew-neovim/issues/149

これはluaのlpegというパッケージが無いという内容。
luarocksというluaのパッケージマネージャで依存パッケージをインストールする。lpegとmpackの二種類が必要。

luarocks install lpeg
luarocks install mpack

これで無事インストールできた。
