Brew failed due to wrong libgit2 version?

[robertkelvey]

I was trying to homebrew install xake on a mac, but ran into an error. The following is copy-pasted from terminal:

github.com/libgit2/git2go

src/github.com/libgit2/git2go/git_dynamic.go:10:3: error: "Invalid libgit2 version; this git2go supports libgit2 v0.25"

error "Invalid libgit2 version; this git2go supports libgit2 v0.25"

^
1 error generated.

If reporting this issue please do so at (not Homebrew/brew or Homebrew/core):
https://github.com/ximeraproject/homebrew-xake/issues

I have libgit2 v0.26 installed. Is there a way to update xake so that it uses this newer version of libgit2?

Here is some extra information, although I don't know if it will help or not. I ran brew update, brew config and brew doctor. Here are the results:
